CD16 Monoclonal Antibody (3G8), NovaFluor™ Yellow 610, eBioscience™, Invitrogen™

Mouse Monoclonal Antibody

This 3G8 monoclonal ab reacts with human and Non-human Primate CD16,also known aslow-affinity Fc gamma RIII. CD16 exists as two distinct isoforms, Fc gamma RIIIA and Fc gamma RIIIB. In humans, Fc gamma RIIIA is expressed as a polypeptide-anchored form on monocytes, macrophages, and lymphocytes such as NK cells. T and B cells do not express this Fc receptor. Fc gamma RIIIB is also detected on neutrophils as a GPI-anchored form. Expression of CD16 on lymphocytes and monocytes is similar in Non-human Primates. However, while CD16 is not found on neutrophils in macaques and baboons, this receptor is detected on these cells in sooty mangabeys. Binding of IgG leads to activation of signal transduction pathways, resulting in ab-dependent cell-mediated cytotoxicity(ADCC), phagocytosis, cytokine release, and antigen presentation.

Based on cross-blocking studies 3G8 recognizes the same epitope as CB16. However, 3G8 and B73.1 ab clones bind distinct epitopes. Applications Reported: This 3G8 ab has been reported for use in flow cytometric analysis. Applications Tested: This 3G8 ab has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at 4uL(0.6ug) per test. A test is defined as the amount(ug) of ab that will stain a cell sample in a final volume of 100uL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
