Recombinant Human FCGR3B Protein (Thr20-Gln208), C-10×His-tagged

Product Description

Cat

IMP-9693

Official Symbol

FCGR3B

Product Overview

Recombinant human Fc gamma RIIIB/CD16b protein (Thr20-Gln208) with a C-terminal 10-His tag was expressed in Mouse myeloma cell line.

Description

The protein encoded by this gene is a low affinity receptor for the Fc region of gamma immunoglobulins (IgG). The encoded protein acts as a monomer and can bind either monomeric or aggregated IgG. This gene may function to capture immune complexes in the peripheral circulation. Several transcript variants encoding different isoforms have been found for this gene. A highly-similar gene encoding a related protein is also found on chromosome 1.
