ADCP Assay Services Antibody-dependent cell-mediated phagocytosis (ADCP) is an important mechanism of action (MOA) of therapeutic antibodies. As a result, these assays are diffi cult to establish in quality-controlled, drug development settings. Antibody-dependent cellular phagocytosis (ADCP) is a mechanism by which macrophages contribute to antitumor potency of monoclonal antibodies. Antibody-dependent cellular cytotoxicity (ADCC), also referred to as antibody-dependent cell-mediated cytotoxicity, is a mechanism of cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies. These assays are laborious and highly variable due to their reliance on donor primary cells, complex assay protocols and unqualifi ed assay reagents. Accordingly, ADCC and ADCP induced by anti-HIV envelope gp120 IgG have been correlated to the limited success of the HIV-1 phase III vaccine trial RV144. ADCP results in the internalization and degradation of the target cell through acidification of the phagosome and, with that, clearance from the body. Phagocytosis is an immunologic mechanism involved in apoptosis, necrosis, infection and tumour conditions that is mediated by leukocytes such as macrophages, DCs, neutrophils, etc. As a result, these assays are diffi cult to establish in quality-controlled, drug development settings. ADCP is an important in vivo MOA of therapeutic antibodies, which can be mediated by monocytes, macrophages, dendritic cells, and neutrophils (effector cells) through multiple FcγRs. The assay consists of Jurkat cells stably expressing human FcγRIIa-H (the high-affinity H131 variant) and NFAT-induced luciferase. It is one of the mechanisms through which antibodies, as part of the humoral … In vivo , ADCP can be mediated by monocytes, macrophages, neutrophils and dendritic cells through FcyRIIa, FcyRI and FcyRIIIa. The FcγRIIa-H ADCP Reporter Bioassay is a biologically relevant MOA-based assay that can be used to measure the potency and stability of antibodies and other biologics that specifically bind and activate FcγRIIa. These assays are laborious and highly variable due to their reliance on donor primary cells, complex assay protocols and unqualifi ed assay reagents. This ADCP protocol may be further used to discern CIR:antibody binding from covalent adduct formation (Alternate Protocol 3). Illustration of the iQue® Human Antibody-Dependent Cellular Phagocytosis Kit assay principles. Herein, we studied the NK cell independent effect of elotuzumab on tumor-associated macrophages using a xenograft tumor model deficient in NK and adaptive immune cells. Robust and Customizable ADCP Assay Solutions. Target cells labeled with iQue® Proliferation and Encoding (B/Green) Dye are incubated with test antibody in 96- or 384-well plates prior to the addition of unlabeled effector cells (either PBMCs or an enriched population of monocytes or macrophages). At Sartorius, we offer ADCP using the iQue screener plus. Figure 1. Antibody Dependent Cellular Phagocytosis (ADCP) Assays. Antibodies mediate a broad array of non-neutralizing Fc-mediated functions against HIV-1 including antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP). Analysis of CIR:antibody target‐specific immune activation is demonstrated with a flow cytometry‒based antibody‐dependent cellular phagocytosis (ADCP) assay (Basic Protocol 3).
