Description: CD16 (FcgammaRIII) is a 50-65 kDa glycoprotein serving as a low affinity IgG receptor.Human FcgammaRIII is expressed in two forms FcgammaRIII-A and -B. FcgammaRIII-A isa transmembrane protein of monocytes, macrophages, NK cells and a subset of T cells. It isassociated with FcepsilonRI-gamma subunit and is responsible for antibody-dependent NKcell cytotoxicity. Mast cell FcgammaRIII-A is associated, moreover, with FcepsilonRI-betasubunit. Besides IgG, FcgammaRIII-A can be triggered also by oligomeric IgE.FcgammaRIII-B is a GPI-linked monomeric receptor expressed on neutrophils and isinvolved in their activation and induction of a proadhesive phenotype.

Specificity: The antibody MEM-154 reacts with the epitope on CD16 antigen that residing in proximity toFG loop (probably BC or C'E loop). CD16 is a low affinity receptor for aggregated IgG(FcgammaRIII antigen). The antibody MEM-154 reacts with CD16+ granulocytes.HLDA V, WS Code M MA068HLDA V, WS Code NK NK51

Application Details

Application Notes: Flow Cytometry: Recommended dilution: 5-10 µg/ml. Positive control: PBL (peripheral blood lymphocytes). Application note: The antibody MEM-154 does not react with CD16a present on NK cells inmany subjects. Application note: Non-reducing conditions. Functional Application: The antibody MEM-154 blocks binding of human IgG to FcgammaRIII.
