SCIEX

Quantitative protein expression analysis is essential for advancing mRNA therapeutics, providing the data needed to confirm effective and targeted protein production. This article explores key assay development strategies, analytical challenges, and the application of advanced liquid chromatography-mass spectrometry (LC-MS) techniques to achieve precise and reproducible quantitation of proteins expressed from mRNA therapies.

Nitrosamine contamination in pharmaceuticals has become a major regulatory concern due to their potent carcinogenicity, requiring ultra-trace-level detection to ensure patient safety. Advanced LC-MS/MS workflows provide the necessary sensitivity, selectivity, and robustness to accurately quantify nitrosamine drug substance-related impurities (NDSRIs), even within complex pharmaceutical matrices. Case studies with betahistine, orphenadrine, and chloropyramine demonstrate how streamlined LC-MS/MS strategies can reliably detect and confirm nitrosamine impurities well below regulatory thresholds.

This infographic explores the benefits of Acoustic Ejection Mass Spectrometry (AEMS)- based workflows for efficient small and large molecule screening.

Charge heterogeneity is present in most biopharmaceutical protein products. During the manufacturing process, charge heterogeneity of the protein therapeutics can occur due to enzymatic cleavage and chemical post-translational modifications (PTM). For therapeutics like ADCs, not only the antibody contributes to the heterogeneity but also the linker and payload, which add even more complexity to the charge variant profiles. Characterizing the charge heterogeneity of ADCs is essential for critical quality attribute (CQA) assessment to ensure drug safety, efficacy, and potency.
