Protein-based biotherapeutics, including monoclonal antibodies (mAbs) and antibody-drug conjugates (ADCs) are a growing component of pharmaceutical companies’ drug pipelines. The growth of ADCs in particular is due to their ability to selectivity target and deliver a...
The stability of peptide and protein biotherapeutics directly impacts their pharmacokinetic profile, efficacy, and safety. It is therefore essential to characterize the stability of a given bio-therapeutic including both in-vivo and in-vitro catabolism, thereby...
There is a lot you can tell from a droplet of blood as it’s snapshot of what could be present in a body at any given moment. In the following application note, LC-MS/MS Screening of 64 New Psychoactive Substances Using Dried Blood Spots, researchers did just...

There is nothing like the flavor of fruit juice whether freshly squeezed or made from concentrate to clench your thirst, except when it’s not 100 percent juice after all. As the following tech note, “Authenticity Assessment of Fruit Juices using LC-MS/MS and...
‘Superbugs’, or bacteria that have developed antibiotic resistance as a result of adapting to the drugs used in their treatment, are dangerous infections that doctors struggle to stop from spreading. Even common infections such as urinary tract infections and...
Photo owned by ProCan A key goal of the ‘Cancer Moonshot’ initiative is the advancement of precision medicine, with the goal of making more targeted therapies available to more cancer patients. And researchers believe that the time is right, with the new technological...
Are you looking for ways to up the ante on your LC-MS/MS when it comes to food testing? Researchers here have developed a method for the analysis of approximately 400 pesticides in food samples, and their work is available for viewing in this year’s compendium. This...
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...
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...
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...
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...
