The Antibody-Dependent Cellular Cytotoxicity (ADCC) Assay incorporates real Effector to Target ratios (NK Cells: Leukemic Cells) to capture the activity of these monoclonal antibodies mediated by cells displaying Fc receptors, such as NK cells and macrophages, evaluating their depletion results based on the quantification of live cells. Initial target quantification is evaluated by Flow Cytometry to correlate with the ex vivo activity.
