Characterization and quality control of monoclonal antibodies (mAbs) is essential to ensure their efficacy and safety. Analytical techniques, like HPLC and mass spectrometry, are vital to assess various properties, such as aggregation, charge variants, and post-translational modifications (PTMs). Our extensive selection of products supports the detailed analysis and evaluation of mAbs to maintain quality and effectiveness.

Intact Mass Analysis of Monoclonal Antibodies

Intact mass analysis of monoclonal antibodies is performed to determine accurate molecular weights of mAb proteoforms for characterization and quality control of the mAb. This technique analyzes mAbs in their intact state using high-resolution mass spectrometry to confirm amino acid composition and detect heterogeneities and glycoforms.

Discover our wide variety of products to monitor the quality and verify consistency in your mAb workflow, including high-performance size-exclusion columns (SEC), ion exchange columns, reversed-phase columns, HPLC buffers, MALDI matrices and standards, high-purity solvents, reagents, tools for protein sample preparation, and reference materials.
