In this application note, we demonstrate the effect of organic solvent on SEC analysis of an ADC “mimic.” This sample is a monoclonal antibody that has been conjugated to a dansyl group and functions as a surrogate for the typically cytotoxic agent commonly used for most ADC modalities.
In this application note, we demonstrate the use of SEC-HRMS for the characterization of NIST mAb RM 8671, a commonly used standard monoclonal antibody surrogate for method development.
In this application note, we demonstrate the use of SEC-HRMS for the analysis of an IdeZ-digested mAb.
Size exclusion chromatography, or SEC, is a technique for separating proteins and other complex biomolecules in their native forms by size using aqueous eluents. For molecules of specific molecular weight, SEC can use used to detect and quantitate aggregates, fragments, monomers and dimer. This guide provides an overview of the Biozen SEC Size Exclusion Chromatography Columns for the analysis of monoclonal antibodies, biosimilars and other biomolecules
