Post-Translational Modification Analysis of Monoclonal Antibodies

Post-translational modification analysis of monoclonal antibodies (mAbs) assesses product consistency, efficacy, and safety. To identify and quantify PTMs in mAbs, mass spectrometry and chromatography are commonly used. High-purity solvents are used to prevent contamination and ensure consistency. HPLC columns separate and quantify different components of the mAb sample. Analytical reagents are used for characterization and detection of mAbs. Glycobiology profiling tools are used to analyze the carbohydrate structures of mAbs.

We offer all the tools you need to monitor and ensure the consistency, quality, and safety of mAbs across various stages of the mAb production workflow.
