Abstract

Abstract Having a functional bioassay that is MOA-based, accurate, precise, robust and reproducible is critical for the development of antibody-based biologics. We have developed reporter bioassays that meet these criteria for a broad range of antibody modalities including Fc effector function, immune checkpoint modulation, bispecific antibody engagement, cytokine modulation, and others. Here we will present the latest technology advancements and bridging of the PBMC based ADCC cell killing assay with reporter based ADCC Bioassay.
