Top Five Misconceptions about Mass Spectrometry
Do you work in a lab handling precious samples yet, hesitant to make the move to mass spectrometry? Many laboratories just like yours continue to conduct sample analysis using ELISA assays, PCR scans, and amino acid tests because of their effectiveness. These processes work, so why change? Well, these type of analytical experiments can report false positive and negative results. You have trained your staff, know the process, and fingers crossed, not too many user errors have compromised analysis.

Stoller Biomarker Discovery Centre, Addressing Some of the Biggest Issues in Medicine
The Stoller Biomarker Discovery Center, developed in partnership with SCIEX, was created to develop new omics technologies for biomarker research to understand the root cause of diseases such as cancer, cardiovascular disease, and autoimmune diseases. We initially announced our collaboration with the University of Manchester back in October 2015.

Rapid Separation Method for Intact Monoclonal Antibodies (Mab) Merges Charge Variant, Impurity, and Glycoform Analyses into a Single Assay
Throughout all stages of development and manufacture, monoclonal antibodies (mAbs) exhibit a great deal of structural complexity. After translation and folding, proteins undergo post-translational modifications, as well as spontaneous and enzymatic degradation, such that a single preparation of purified mAb exhibits a range of small structural changes, composed of various glycoforms and charge variants, as well as amino acids alterations due to oxidation, deamidation, isomerization, or other chemical reactions. This display of structural heterogeneity can influence the overall stability, efficacy, and safety profile; therefore, understanding the extent of structural modifications has become extremely important to drug manufacturers who continually assess mAb composition throughout bioprocessing to demonstrate stability, batch-to-batch consistency, and long-term shelf life.

Glycosylation Analysis Designed for the (Protein) Masses
A variety of post-translational modifications (PTMs) can impact a biotherapeutic protein’s mass, but none are as common as glycosylation.[1] Hence, the headline for a recent article in Genetic Engineering and Biotechnology News, “Post-Translational Icing on the Biologics Cake,” featuring comments from Sean McCarthy, Ph.D., Global Market Manager of Biologics at SCIEX.

The History of Isotopic Labels for Quantitative Proteomics
Proteomics has become a vital tool for biological scientists performing research on the healthy and diseased states of living things. It involves the large scale and systematic analysis of all proteins within a given cell, tissue, or organism. Because proteins are regulated by many different internal and external stimuli, the proteome is dynamic and quantities of proteins can change from one state to the next. Therefore, in order to be of the highest utility, proteomics experiments need to both identify and quantify proteins so that comparative studies can be done, such as between healthy cells and tumor cells, or the comparison of different treatment regimens.

Integration of Electrophoresis into a Single, “Plug-and-Spray” Device Offers a New Approach for Metabolomics Applications
Teasing apart the metabolome: CESI-MS separation of small, anionic compounds
Metabolomics, an emerging field focused on the chemical processes central to cellular metabolism gives scientists a snapshot of the cellular metabolic state, or metabolome at a given time. Highly complex, the metabolome contains a large and diverse group of small molecules and requires a systematic understanding of chemical end-products of cellular processes. Used in conjunction with genomics and proteomics information and researchers can gain a deeper understanding of an organism’s physiology. As a result, insights on a disease’s progress or an organism’s health status become clearer. However, there is a caveat. Teasing apart metabolome components and identifying each molecule is a significant analytical challenge that requires specialized applications and approaches able to separate very small, chemically similar analytes from each other.

Struggling to Analyze Small Volume Samples with Conventional LC-MS?
The M3 MicroLC System is designed for scientists who are struggling to analyze small volume samples with conventional LC-MS and need to lower their limits of quantitation while maintaining throughput and robustness. When designing the M3 MicroLC System, we focused on creating an easy-to-use LC that would make microflow LC simple – even for those new to […]

Legal and Illicit Drugs in Wastewater Detected and Confirmed with QTRAP Technology
What happens when you up the sensitivity and lower detection limits on influent and effluent sewage tests? For starters, low levels of illegal drugs in samples begin to emerge. This is what researchers discovered when they combined the power of LC-MS/MS with the Scheduled MRM™ algorithm using large volume injection techniques on a QTRAP® 5500 system. Limits […]
