Native MS for Aggregate and Charge Variant Analysis of Biotherapeutics

Register free: http://www.chromatographyonline.com/lcgc_w/charge_variant

Event Overview:
Size exclusion chromatography (SEC) and ion exchange chromatography (IEX) are classic techniques employed in the characterization of biotherapeutics under non-denaturing conditions. Standard mobile phase conditions for these techniques are high in salt concentration, rendering them incompatible with mass spectrometry (MS) detection. Native mass spectrometry (MS) represents a cutting-edge approach to employ MS-compatible mobile phases for non-denaturing SEC and IEX analysis. This webcast will discuss aggregate and charge variant analysis using native mode MS.

Key Learning Objectives

• Understand fundamentals in SEC and IEX for biotherapeutic characterization

• Effect of mobile phase conditions and chromatographic parameters in aggregate analysis by native SEC

• Determination of acidic and basic variants of monoclonal antibodies using native weak cation exchange chromatography (WCX)
