Biolegend, 149521, Brilliant Violet 421™ anti-mouse CD16.2 (FcγRIV) Antibody, 50μg

FcγRIV, also known as CD16.2, is an intermediate-affinity activating receptor for IgG2a and IgG2b. CD16.2 is the mouse homolog of human FcγRIIIA. CD16.2 is a low-affinity IgE receptor for all allotypes and the ligation of FcγRIV by antigen-IgE immune complexes promotes macrophage-mediated phagocytosis and is involved in lung inflammation.
