Progenesis QI for proteomics 5-star review

How was Progenesis QI used in an untargeted lipidomics workflow?

Following on from last month’s blog post, I’d like to continue with the other exciting video presentation from ASMS 2019. Dr. Jace Jones from the University of Maryland, School of Pharmacy, Department of Pharmaceutical Sciences in Baltimore, Maryland gave a very interesting talk on how the Progenesis QI software was used effectively and robustly to process a variety of lipidomic datasets from a traumatic brain injury model. His talk was entitled: The Use of Progenesis QI to Efficiently Process Lipidomic Data: Application to Traumatic Brain Injury

At a first glance, people only see what they want to see as we are preprogrammed to view things from our own perspective. The same can happen in science where we look at what we know over and above what we don’t. Dr. Jones highlighted the fact that the Progenesis QI software facilitates a process for them to be able to see what is not always visible at first so they could focus on groups that may not have been obvious.

After using the Progenesis QI software in his discovery workflow he then went on to do his quantitation workflow which corresponded well with the discovery results. This gave him great confidence that his workflows were robust in that he could go back and forth between discovery and quantitation.

The abstract for the talk Dr. Jones gave is below, but I again highly recommend you watch the video as the work they are doing can have a big impact on how we treat traumatic brain injuries moving forward.

The Use of Progenesis QI to Efficiently Process Lipidomic Data: Application to Traumatic Brain Injury

Jace W. Jones, Ph.D.

University of Maryland, School of Pharmacy, Department of Pharmaceutical Sciences, Baltimore, MD

Lipids have significant potential to inform on disease and injury due to the pivotal role they play in many biological processes including cellular integrity and permeability, energy storage and metabolism, and signaling pathways. Heightened interest in the mechanism by which disruption of lipid metabolism and homeostasis contributes to a variety of human diseases and injuries (e.g., cancer, diabetes, neurodegenerative disorders, infectious diseases, and pulmonary conditions) has led to a substantial increase in lipidomic research. The field of lipidomics, broadly described as the comprehensive biochemical characterization of “all” lipids (referred to as the lipidome) within a cell, tissue, or organism presents a variety of analytical and data processing challenges. The analytical challenges result primarily from the dynamic range, vast structural diversity, and sheer number of biological lipids. These challenges have been commonly addressed using liquid chromatography coupled to high resolution tandem mass spectrometry. This workflow results in an information-rich data matrix that must be processed for retention time alignment, peak picking, adduct deconvolution, abundance, identification, and statistical analysis. Successful implementation of the aforementioned lipidomic workflow in a model system where two appropriate cohorts (e.g., disease vs control) are comparatively analyzed yields differential expression data delineating lipid profiles between the two groups and abundance of individual lipids.

The data processing challenges associated with efficiently and properly handling lipidomic data is not trivial and has been meet with a variety of software solutions. One such software solution is Progenesis QI from Nonlinear Dynamics (Waters). Progenesis QI offers a comprehensive workflow for efficiently processing LC-MS/MS generated lipidomic datasets. Progenesis QI is streamlined to handle multidimensional data in the form of chromatographic retention time, ion mobility, accurate mass, and data-independent acquisition. Data will be presented detailing the use of Progenesis QI to effectively and robustly process a variety of lipidomic datasets from a traumatic brain injury model.

Please get in touch or comment below.

Are you missing out on how Progenesis QI can help your research?

ASMS 2019 has come and gone but the research continues. Nonlinear and Waters were lucky to have speakers at ASMS 2019 who shared their research with us and explained how the Progenesis QI software was an integral part of their work.

If you didn’t get to attend the talk by David W. Gaul, PhD., from the Georgia Institute of Technology or would like to hear the presentation again then we have the video for you. The title of his talk was “Preoperative Metabolomic Signature of Prostate Cancer Recurrence” To get an idea of what the presentation entails, you can read the abstract below, but I highly recommend you watch the video so you can see how important the work David and his group are doing with regards to giving people more information on how they can change their treatment decisions moving forward from a simple blood test.


Up to 50% of prostate cancer surgical patients will suffer from biochemical recurrence manifested by detectable serum prostate specific antigen levels even after prostate removal. Currently available pre-operative information has not yielded adequate prognosis to guide a patient’s treatment decision.  More clinical data is needed to improve prognosis. New biomarkers can arise from metabolome analysis of patient serum to aid physicians and patients in developing a treatment plan. We applied a multiplatform (NMR + LC−MS) metabolomics approach to the study of preoperative metabolic alterations associated with prostate cancer recurrence.

Identification scoring in Progenesis QI

With the amount of information available today, important and helpful information can easily get lost and overlooked. I’d like to take this opportunity to repost this blog post about identification scoring in Progenesis QI of as many of our customers find this very useful in their research and still refer to it today.

One of the advantages of using Progenesis QI is its ability to combine results from multiple search methods and databases. Progenesis QI uses a common scale to score results from all the databases and search methods it supports, so you can compare search results obtained from different search methods. This post explains the scoring method we use in Progenesis QI, and how you can improve your search scores by searching additional dimensions of your data.

Progenesis QI search methods

At the time of writing, Progenesis QI supports these search methods and databases:

Progenesis MetaScope

Searches SDF and MSP files from any source. Supports retention time, CCS, theoretical fragmentation and spectral libraries.

METLIN™  MS/MS Library (requires purchase)

The Waters® METLIN™ MS/MS Library for Progenesis QI contains a local copy of the METLIN database and allows you to search this copy rapidly.


Searches the LipidBlast MS/MS database provided by Metabolomics Fiehn Lab.

Elemental composition

Produces putative formulae for compounds based on mass, isotope profile, and the Seven Golden Rules.


Searches the ChemSpider structure database. Supports theoretical fragmentation, isotope similarity filtering, and elemental composition filtering.

NIST MS/MS Library (requires purchase)

Searches the NIST MS/MS library for spectral matches.

You can find out more about each of these search methods in the search methods and databases FAQ. This blog post, however, will focus on how we calculate scores so that identifications from different search methods can be compared.

The Progenesis scoring method

For any given search, there are a possible five properties that can contribute to the overall score:

  1. Mass error
  2. Isotope distribution similarity
  3. Retention time error
  4. CCS error
  5. Fragmentation score

Each of these individual scores is on a scale from 0-100. If your search criteria do not include a given piece of data, the score for that piece of data is 0. The overall score is the mean of these 5 scores.

Note that the more search criteria you use, the higher the maximum possible score becomes, as described in the following example.


Suppose we have searched ChemSpider using theoretical fragmentation. For a given compound we find Identification A, with these scores:

Note that the scores for retention time and CCS errors are 0, because ChemSpider does not support searching those properties.

If we then perform a MetaScope search, this time including a CCS constraint, we might obtain the following scores for Identification B:

We have identical scores for the mass error, isotope distribution, and fragmentation. However, we also have an extra piece of information in the CCS score. This provides additional evidence for Identification B, so it is given a higher score than Identification A.

Note that in the ChemSpider case, if an identification scores 100 on all 3 items, it obtains a score of 60. In the MetaScope case, if an identification scores 100 on all items, it obtains a score of 80. So, for each additional piece of data we include in our search, the maximum score increases by 20.

The component scores

Here we’ll briefly describe how the five component scores that make the final score are calculated.

Mass error, retention time error, and CCS error

These are all functions of the magnitude of the relative error, Δ:

The score profile for mass error, retention time error and CCS error.
Figure 1: The score profile for mass error, retention time error and CCS error.

For the mass error, Δ is the ppm mass error and N = 4000. For the retention time and CCS errors, Δ is the percentage error, and N = 20.

Isotope distribution similarity score

This compares the intensities of each isotope between observed and theoretical distributions. A total intensity difference of 0 gives a score of 100, which falls linearly to 0 when the total intensity difference is equal to the maximum isotope intensity.

Fragmentation score

The fragmentation score is more complicated and depends on the fragmentation method used. The FAQs describe how scoring works for theoretical fragmentation and database fragmentation.

Improving identification scores

The best way to improve the scores of your identifications and your confidence in them is to use more search constraints.


In general, most searches will be able to produce a mass error score and an isotope similarity score. With just these two pieces of information, the maximum score for any identification is only 40/100. In this example we’ve identified Warfarin using only mass error and isotope similarity.


By including fragmentation data in your search criteria (either theoretical fragmentation or a fragmentation database), this increases the possible score for identifications to 60/100. Here we’ve added theoretical fragmentation to our search parameters.


Finally, if you use an appropriate data source (e.g. an SDF and additional properties file) you can add search constraints for retention time and CCS, giving a maximum score of 100/100. Here we don’t have CCS information but have added retention time to our search parameters for a maximum of 80/100.

Future improvements

Currently Progenesis gives equal weight to the five component scores – mass error, isotope similarity, fragmentation score, retention time error, and CCS error. In some cases, this might not be ideal, so if you have any suggestions for different weightings we’d love to hear from you in the comments section below.

As always, if you have any further questions, check our FAQ or get in touch.

How do you know your raw materials are as they should be?

Agnès Corbin of Nonlinear Dynamics gives us an overview of what’s needed to maintain high manufacturing standards.

Agnes Corbin

We all know it, reproducibility is one of the key parameters to master for maintaining a product’s quality. As a customer, we all like our favorite products of a consistent high quality; as a manufacturer, we want to preserve our quality and customers’ satisfaction

That starts with the supply chain of the raw materials and ingredients used to manufacture a finished product.

A non-conformity, be it a cross-contamination, adulteration or degradation, can have huge economic, clinical and sanitary consequences, especially with high cost raw materials.

With this in mind, you might be interested in the below application note, produced in collaboration with Robertet Group, the world leader in sustainable natural raw materials for fragrance and flavor.

Vetiver essential oils application note

It describes how Progenesis QI was used, to spot an ‘out-of-the-blue’ potential non-conformity in Vetiver essential oil, using an Untargeted Metabolomics Profiling approach with LC-HRMS and a variety of Ionization techniques.

Progenesis QI helped to detect and identify adulteration with Castor Oil, a non-volatile compound, in a new batch of Vetiver Essential Oil. It would have been missed with the use of classical and common GC-MS techniques applied on volatile compounds.

The combination of LC separation equipment UPC² and UPLC (with different ionization sources ESI, APCI, ASAP) were used to get a better understanding of the product’s composition. Suppliers of natural raw materials must increase their phytochemistry knowledge of their products, as per the recent change in the REACH regulation based on the Natural Complexes Substances (NCS).

The easy-to-set-up LC-MS techniques for non-volatile compounds, can be considered as complementary to GC-MS for volatile compounds QC.

Robertet could have missed out if they hadn’t used the Progenesis QI software.

The importance of the surfaceome and its interactors

We love to hear how our customers are using Progenesis QI and Progenesis QI for proteomics. It’s great to learn what they are researching and how Progenesis can help them. It’s also nice to find out more about the people behind the research. Our latest blog post features Dr Maria Pavlou and her interesting work with Dualsystems Biotech AG. First, here’s some background about Maria:

Dr Maria Pavlou

Maria Pavlou received her PhD in translational proteomics from the Department of Laboratory Medicine and Pathobiology at University of Toronto, Canada. Upon PhD completion, Maria moved to Switzerland to pursue a post-doctoral fellowship in the Institute of Molecular Systems Biology at the Swiss Federal Institute of Technology (ETH) in Zurich focusing on host-pathogen interactions. In 2017, she joined Dualsystems Biotech AG as a senior scientist and a year later, she was promoted to Chief Scientific Officer leading the research team to develop further the Ligand-based Receptor Capture (LRC) methodology and establish new services.

Now, onto the research:

The importance of the surfaceome and its interactors

If the plasma membrane is considered the gateway through which cells communicate and interact with their environment, then proteins associated with the surface – referred as the surfaceome – can be seen as the gatekeepers. The surfaceome largely dictates the shape, polarity, differentiation and motility of cells. It also mediates cellular behaviors such as cell-cell communication, self and non-self recognition, and cell signalling. Given the crucial role of surface-associated proteins in every aspect of cellular life, it is not surprising that they are the molecular targets for roughly 70% of FDA approved drugs [1].

The original concept, depicting the plasma membrane as a homogeneous fluid bilayer with freely diffusing proteins, has been evolved to another depicting a highly organized and crowded mosaic of interacting lipids and glycoproteins. This higher organization modulates the biological processes occurring on the cell surface, exemplified by receptors being active only when they form dimers, hetero-dimers or higher order oligomers [2]. Interactions of proteins in the cell membrane of the same cell (cis), and interactions of proteins of neighboring cells, the extracellular matrix and circulating ligands (trans) are collectively referred to as extracellular protein-protein interactions (ePPIs).

Elucidating ePPIs in a systemic fashion is pivotal to gain a better understanding of the surfaceome function. More specifically, identifying the targets of key ligands on the cell surface provides valuable mechanistic information about signal transduction, drug action or off-target effects. For instance, pathogen or growth factor interactions are important for developing novel therapies. Additionally, numerous ligands exist – both biologics and small molecules – involved in biological functions mediated at the cell surface through still unknown protein targets.

Towards target identification, an advanced cell-based chemo-proteomic approach has been developed namely ligand-based receptor capture (LRC) [3-4]. In this approach, the endogenous receptor repertoire of a given cell serves as an existing bait library that can be probed for ligand interaction. The key component of the LRC methodology is a trifunctional compound (TriCEPS or its latest development named HATRIC [3-4]) that utilizes the extensive glycosylation displayed by the majority of cell surface proteins to capture receptor interactions on living cells. Experimentally, the first arm of TriCEPS is conjugated with the primary amines of a ligand and the conjugates are added on living cells (mildly oxidized). There the ligand binds to its target(s) and the second arm of TriCEPS is covalently crosslinked to the glycans of the binding partner. The third arm facilitates target purification for mass spectrometric analysis.

In a typical LRC-TriCEPS experiment, at least two treatment arms are performed in parallel: one with the ligand of interest and a second with a control ligand (that is, a ligand with a known target). Upon identification, the relative abundance of cell surface proteins in the ligand samples is compared to those in the control samples using MS1-based label-free quantification. Randomly identified cell surface proteins are expected to have equal abundance in both samples, whereas the corresponding receptors are found enriched in the ligand sample.

Progenesis QIP gives the user full control but does not require advanced computational skills

Progenesis QI for proteomics (QIP) has been the workhorse when it comes to data analysis. Performing MS1-based label-free quantitation in Progenesis is extremely straightforward through an intuitive user-friendly interface.

The alignment of features is performed by sophisticated algorithms but at the same time the software provides the user with visual inspection of the whole procedure. This is extremely useful as the user has full control of the data and a better understanding on how the samples are processed. It can also reveal technical issues related to the liquid chromatography separation prior to mass spectrometric analysis or sample quality. Notably, proper feature alignment is pivotal for robust quantitation. Moreover, the feature-picking algorithm (peak picking) has been developed to minimize missing values therefore the requirement for imputation; another asset for robust quantitation.

Through the various filtering options, the user can eliminate features that are not of interest (such as polymers or contaminants) focusing on what really matters. The QC metrics tab provides a qualitative overview of the experiment giving the opportunity (once more) to assess whether the LC and MS parameters used were optimal.

Upon protein inference and calculation of relative abundances, the user can easily review protein characteristics (such as number of peptides, peptide sequence and modifications, expression profiles, see figure 1) and confirm results or flag outliers. Once more, this option gives the user full control over the data and eliminates, to a great extent, experimental artefacts.

LRC-TriCEPS analysis to identify the receptors of Insulin and Transferrin on HEK293 cells; a screenshot of Progenesis QIP.

Two LRC experiments were performed using insulin and transferrin as ligands of interest on HEK293 cells with receptor capture at two different pH (6.5 and 7.4).

(A) Following the intuitive and straightforward progenesis pipeline, the identification and quantitation (MS-1 based) was completed within 6 hours.

(B) A total of approximately 300 surface proteins were identified and quantified across all samples. Transferrin receptor (TFR1), the known target of Transferrin, was also identified with roughly 40 unique peptides.

(C) Using the protein filter the relative abundance of TFR1 across the four conditions was visualized; TFR1 is clearly enriched in the Transferrin samples.

(D) For more detailed information the user can check the quantitation of every peptide identified and spot any irregularities.

(E) The user can use the statistics run by Progenesis or export the data for post-hoc analysis.

As statistical testing is incorporated in the software, the final outcome of an analysis provides immediate information regarding proteins being significantly regulated. However, there is still the option to export all necessary information in order to perform post-hoc statistical analysis using different tools. This increases greatly the flexibility of the user.

Finally, Progenesis QIP is readily scalable when it comes to number of samples and performs analysis in a time-efficient manner, allowing for complete label-free quantitation in the course of a working day. This is extremely important given that data analysis is usually the beginning of a series of experiments aiming to verify and interpret the identified quantitative differences. It provides a variety of different plots and graphs that can be readily used for publications or reports.

In summary, the analysis of LRC-TriCEPS data with Progenesis QIP offers unique advantages. The software is user-friendly and intuitive therefore can be used by researchers with experience in data analysis but also by users that are just starting or do not perform data analysis daily. Progenesis QIP provides the user with full control over data analysis which is very important to spot and resolve experimental artefacts and to understand how the final outcome is reached. At the same time, the sophisticated algorithms provide high quality label-free quantitation and robust results. Finally, the nice visualization aspects can generate high quality graphs that can be used to communicate the results of each study.

A Progenesis QI workflow in Exposomics

Following on from the previous post about our 3 Progenesis QI lunchtime presentations at IMSC 2018, we are proud to present to you the talk given by Emilien Jamin from the Toxalim, Research Centre in Food Toxicology, Toulouse University, available to view here.

Emilien’s work in contaminant discovery and analysis shows how Progenesis QI can be used very effectively for untargeted analysis in the Exposomics field.   This workflow goes beyond suspect screening which requires prior knowledge.  Emilien uses several examples of how Progenesis QI was used to discriminate between different populations and finally touches on a proof of concept on lipids peroxidation.

You can view the talk for yourself and you can read an overview of his presentation below.

In food safety, current exposure assessment approaches are based on food consumption data crossed with food contamination data or biomonitoring data. This allows evaluating exposure only in a targeted way on a few families of compounds. Based on our previous results in exposomics [1], food or environmental toxicology should focus on the exposure to a mixture of compounds (contaminant cocktails), mostly at low doses, and in an untargeted way to detect/identify unknown compounds. And among these numerous known and unknown metabolites, it seems a priority to focus on potentially toxic compounds.

In this context; we developed an untargeted method using high resolution mass spectrometry coupled to liquid chromatography to specifically profile electrophilic metabolites, in parallel with a classic untargeted metabolomic study. This allows the study of the exposure of potentially toxic compounds on one hand, and the study of the effects of this exposure on the endogenous metabolites on the other hand. More precisely, we used the MSE mode of a Synapt G2-Si mass spectrometer to detect all the metabolites displaying a neutral loss specific of metabolites conjugated with mercapturic acid. Data from MSE and from untargeted HRMS analyses were processed with Progenesis QI, to highlight discriminant reactive metabolites, as well as endogenous metabolites.

As a proof of concept, this approach has been applied to the study of different groups of rats fed diets containing various oils. According to our previous results on lipid peroxidation [2] these diets led to the production of different aldehydes conjugated to mercapturic acid. The most well known is DHN-MA which corresponds to the mercapturate conjugate of 4-hydroxynonenal (4-HNE), which is commonly used as a biomarker of lipid peroxidation [2]. Using our methodology, we were able to detect without a priori, dozens of mercapturate conjugates, including DHN-MA and other known conjugated aldehydes. Furthermore, our approach also allowed the detection of conjugates of unexpected aldehydes, and of other chemical classes, for which putative identifications have been proposed based on complementary structural analyses. Interestingly, multivariate statistical analyses of the HRMS signals carried out on the mercapturate conjugates yield a better characterization of the studied animal groups compared to results obtained from a classic untargeted metabolomic approach.

Novel Strategies for Discovery of Cardiovascular Biomarkers in Human Plasma

Background: The search for blood-based biomarkers is particularly compelling in the cardiovascular clinical arena. Whilst understanding the genetic basis of cardiovascular disease will provide a clear indication of risk, phenotypic markers represent the pathological changes that occur during disease processes. Methods for investigating the plasma proteome have ostensibly relied on complex pre-analytical protocols that are expensive and limit throughput.

Methods: 100 Coronary heart disease Patients with 20 healthy control were analyzed on the SYNAPT G2-Si, using label-free data-independent acquisition LC-MS with ion mobility optimized (HDMSE). Samples were treated with Calcium Silicate matrix (CSM). Raw data was then analyzed using Progenesis QI for Proteomics. Models of panels of markers were developed using SPSS and RapidMiner.

Results: From 50 µL of plasma, in excess of 1800 proteins are realized that can be reliably observed between samples. Of these, >1100 are quantified. The data shows high reproducibility with known differences predictably demonstrated. New markers are revealed which can be strongly aligned with potential novel mechanisms of coronary artery disease (CAD). The method is shown to be highly reproducible.

Conclusion: We demonstrate that CSM provides sufficient coverage to enable single shot analysis of plasma, historically, a very challenging proteomic sample to analyze, and can provide potential markers for CAD which could feasibly be extended to several classes of disease. This provides a method that can run alongside other omic technologies to profile large-scale numbers of patients individually and thus usher in a new era of precision medicine. Importantly, there are advantageous savings to be made in terms of cost and throughput, which mean that for the first time large scale cardiovascular cohorts, conducted in a realistic timeframe, can be analyzed using proteomics

Can Progenesis adapt to your application?

Adaptability is a critical factor in research success.  How adaptable is the Progenesis QI and Progenesis QI for proteomics software? The answer is very adaptable. You’ll be surprised to see what different market segments and applications the software has been used for.

Food and environment

In this market sector, the software has been used for food authenticity which is now a major concern across the globe.  This blogpost “Don’t get stung by your Manuka Honey!” Highlights the use of the Progenesis QI software in laboratories that test food to examine the differences between genuine and fraudulent products. For further reading, “Bringing the analysis to the sample: Progenesis QI helps beat food fraud” discusses Professor Chris Elliott’s webinar where he talks about many instances of food fraud including milk, horse meat, oregano, and cumin fraud. Chris speaks about how he works with Progenesis QI to analyze data produced at the Institute for Global Food Security.

Natural products

As with the Food and Environment sector, adulteration is also being seen in the natural products market sector. This blogpost aptly named “Just because it’s natural doesn’t mean it’s safe” describes the webinar on Authenticated Herbal Supplements with a metabolomics approach.  This looks at correctly identifying the marker compounds of each species of Hoodia, Terminalia, and Chamomile to ensure they are the correct substance. The work was carried out with collaboration from Waters and the University of Mississippi. For further reading you can read the relevant paper: Metabolic Profiling of Hoodia, Chamomile, Terminalia Species and Evaluation of Commercial Preparations Using Ultrahigh-Performance Liquid Chromatography Quadrupole-Time-of-Flight Mass Spectrometry.

Chemical and materials science

What value can Progenesis QI provide in the world of co-polymer characterization? Polymeric materials are being used more and more in everyday life. They are being used as structural materials for cars and airplanes, fabrics for clothing, packaging materials for food and medicine, to name but a few. These new materials must be properly characterized in order to manufacture the polymers’ reproducibly and thus achieve the required characteristics.

This blogpost explores using Pyrolysis-Gas Chromatography/Mass Spectrometry (Py-GC/MS) coupled with Progenesis QI’s multivariate analysis of the data, to provide novel insight into the polymer structure.

Figure 3. Following replicate analysis of the two co-polymer samples the data was aligned and peak picked using the workflow presented by Progenesis QI. The resulting data was analyzed using an OPLS-DA model to compare the samples. The scores plot resulting from that analysis is shown here where it can be seen that the two co-polymer types are clearly discriminated.


An exciting application is the use of Progenesis QI for proteomics for Host Cell Protein (HCP) analysis. The blogpost, “Progenesis QI for proteomics speeds up biopharmaceutical purification!” , explains how using the software greatly simplifies the user interaction with HCP datasets. Extracting mass chromatograms and calculating peak areas for a multitude of peptide precursors (like the 113 peptides from the MIX-4 spectral library) can be a tedious process. The data from each individual sample replicates need to be compared in order to obtain the peptide level HCP trends. The HCP peptide level results need to be translated into HCP protein levels. All these steps are automated and they are performed rapidly in the Progenesis QI for proteomics software without significant user intervention. This saves a significant amount of time spent on data analysis, producing rapid results.

Dr. Maartens Dhaenens shares his expertise in using the software when he presented his webinar “Proteomics: A peptides Journey to Emergence”. This blogpost of the same name explains his thoughts about understanding how all the different levels of complexity in proteomics data can be unraveled by the different functionalities of Progenesis QI for proteomics. He extols how Progenesis QI for proteomics is a powerful tool for resolving the many challenges in automated data analysis and protein inference.

We have many happy customers, including Dr. Daniel Carrizo, who uses the Progenesis QI software for his metabolomics research. Daniel uses the Progenesis QI software to assess exposure to persistent organic pollutants (POPs). Daniel comments “The data generated is too complex to analyze without specific software like Progenesis. When you have 3000 or 4000 ions of interest and 300 samples, it is impossible to manage this amount of data with normal software. I have found Progenesis QI is robust and easy to use and the technical support is excellent.” He goes on to say “The most important aspect is the power of the analysis and robustness of the data generated, as well the easy design for setting up experiments within the software.” If you would like to see Daniel’s full blogpost you can read it here.
