A high-throughput hydrophilic interaction liquid chromatography coupled with a charged aerosol detector method to assess trisulfides in IgG1 monoclonal antibodies using tris(2-carboxyethyl)phosphine reaction products: Tris(2-carboxyethyl)phosphine-oxide and tris(2-carboxyethyl)phosphine-sulfide.

Abstract

A robust, high-throughput method using hydrophilic interaction liquid chromatography (HILIC) coupled with a charged aerosol detector (CAD) is reported as a novel approach for trisulfide quantitation in monoclonal antibodies (mAbs). The products of mAb reduction using tris(2-carboxyethyl)phosphine (TCEP) include a species (TCEP(S)) that is stoichiometrically… (More)
