Fc Gamma RIIIB/CD16b (NA1), His, Human

Fc gamma RIIIB/CD16b (NA1), His, Human on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

Fc Gamma RIIIB/CD16b (NA1), His, Human

Fc gamma RIIIB/CD16b (NA1), His, Human, His Tag captured on CM5 Chip via anti-his antibody can bind Rituximab with an affinity constant of 8.55 μM as determined in SPR assay (Biacore T200).

Fc gamma RIIIB/CD16b (NA1), His, Human

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.
