Fc receptor-mediated antibody-dependent cell-mediated cytotoxicity (ADCC) is an important mechanism of action (MOA) by which antibodies target diseased cells for elimination. Traditional methods for measuring ADCC require primary donor peripheral blood mononuclear cells (PBMCs) or purified natural killer (NK) cells that express Fc receptors on the cell surface. Killing of target cells is an endpoint of this pathway activation and is used in classic ADCC bioassays.

PBMCs and NK cells are notoriously difficult to isolate and culture. Furthermore, cultured cells can be a source of variability.

There is a Better Way

Watch this video to learn why traditional ADCC assays can be problematic. You’ll also learn a solution. Find out how  to not only save time but also reduce assay variability.
