Fc Characterization is a critical process in the development and quality control of therapeutic antibodies, focusing on the Fc (Fragment, crystallizable) region of the antibody molecule. This region is responsible for mediating immune effector functions, such as antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). Fc Characterization involves analyzing the glycosylation patterns, binding affinities to Fc receptors, and structural integrity of the Fc region, which can influence the efficacy and safety profile of antibody-based therapeutics.
