High-quality Fc Receptors
The efficacy of a therapeutic antibody not only depends on the Fab fragment and its binding activity to the target antigen, but also depends on the Fc fragment and its interaction with key Fc receptors. The binding affinity of the Fc fragment towards FcRn (FCGRT&B2M) would predict the antibody’s half-life, while that between the Fc fragment and FcγRIIIa (CD16a) would influence the antibody’s ability to elicit ADCC (antibody dependent cell mediated cytotoxicity). Therefore, candidates must be tested against a panel of receptors during antibody engineering. ACROBiosystems offers a comprehensive collection of recombinant Fc receptor proteins, including their common variants, to expedite your antibody drug development.
