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.

Selecting an LC-MS system for quantitation of pharmaceutical drug development
We understand you are busy, needing to prioritize running instruments, reporting results and managing your laboratory to meet deadlines. We created a solution guide to explain how SCIEX systems fit in the drug development pipeline to save you time evaluating options.
Nitrosamines: Where are we now?
Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.
Guide decisions during cell line development with more information at the intact level
Monitoring product quality attributes (PQAs) throughout monoclonal antibody (mAb) development is vital to ensuring drug safety and efficacy. By adopting orthogonal analytical techniques and integrating new technologies that have the potential to provide more information, it is possible to improve product quality and manufacturing efficiency and make more informed decisions.
High complexity of the lipidome
The complexity of the lipidome is diverse in the structure and there are many combinatorial isoforms that are available within nature. Currently, many different techniques are required to fully characterize a lipid molecule. What if you could do it in a single...
Breaking down the SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready
Sensitivity and robustness carry different meanings in the world of mass spectrometry. Generally, sensitivity refers to an instrument’s ability to achieve lower limits of detection (LOD). Robustness, on the other hand, refers to an instrument’s ability to consistently...
The honey sting
As a consumer it’s hard for me not to feel inundated with claims that our food is “all-natural” or “chemical-free” or that we should buy certain “superfoods” for their health benefits. We read labels and trust that the product we are buying is what we are truly...
Innovation that’s blasting through limitations in explosive detection
Mass spectrometry’s important role in identifying explosives The need for rapid explosive detection is now an unfortunate reality. The remit is multifaceted. The first is for preventative purposes, to protect us from any threat to life. The second is in the...
A new generation of therapeutic modalities
There are over 7,000 genetic diseases that could potentially be cured using gene therapy. Rare metabolic diseases, autoimmune disorders, cardiovascular disease and cancers are some of the top disease classes that can be addressed with gene therapies. With over 1,000...
Enhancing Biologics with CESI-MS Characterization
Comprehensive characterization of a biologic requires analysis at both the intact and digest levels, but these analyses can be complex and cumbersome. For example, with conventional liquid chromatography separations, researchers are often left with limited information...
Full, partial and empty capsid ratios for AAV analysis: What’s the big deal?
For many of you working to develop gene therapy drugs, you know that the time to market the drug is critical. Because gene therapeutics cure diseases by targeting specific genes, it is a constant race to see who develops the drug first. Unlike other classes of drugs where multiple medications can be used to treat a disease, whoever is first to develop a gene therapy drug wins.
