Assays to Evaluate Fragment Crystallizable (Fc)-Mediated Effector Function (On-Demand)

Curriculum

Course Description:Fc effector function activities are mediated via interaction of the fragment antigen binding (Fab) domain of a therapeutic monoclonal antibody with the target antigen, and the interaction of the Fc domain with complement or various Fc gamma receptors (FcγR) expressed on cells of hematopoietic origin (e.g., natural killer, macrophage, dendritic, monocyte, and neutrophil). The different Fc-mediated effector function activities may include antibody-dependent cell-mediated cytotoxicity, complement-dependent cytotoxicity, antibody-dependent cellular phagocytosis, and Fc-dependent apoptosis.

This webcast will describe a new, informational USP General Chapter <1108> that is intended to provide users with practical guidance regarding the selection, development, and validation of Fc function assays, including the measurement of low-affinity interactions observed FcγRs and the impact of glycosylation on antibody effector function.

The chapter details in-vitro assays that assess complex Fc domain interactions critical to the biological characterization of Fc-containing therapeutics. Best practices to develop and validate cell-based and non-cell-based formats for measuring these interactions are provided, as well as advantages, disadvantages, and points to consider for each assay format.
