Product Description Recombinant Human Fc gamma RIIIB/CD16b (NA1) Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Gly17-Ser200(NA1).

Product Background

Human Fc gamma RIIIB/CD16b Protein is a receptor for the Fc region of immunoglobulins gamma. Low affinity receptor. Binds complexed or aggregated IgG and also monomeric IgG. Contrary to III-A, is not capable to mediate antibody-dependent cytotoxicity and phagocytosis. May serve as a trap for immune complexes in the peripheral circulation which does not activate neutrophils.
