Fc Binding and Function Assays
Abzena offers a complete solution to support the characterisation of the Fc-mediated activity of your antibody or ADC product.
Fc-mediated effector functions may play a role in the mechanism of action of an antibody or an ADC and have an impact on the product safety and efficacy. For these reasons, both EMEA and FDA guidelines recommend to analyse Fc functions in detail, including binding to Fc receptors and Fc-mediated cytotoxicity such as ADCC and CDC.
