Recombinant Cynomolgus FCGR2B Protein, C-His&C-AVI-tagged

Product Description

Cat

IMP-1999

Official Symbol

FCGR2B

Product Overview

Recombinant cynomolgus (Macaca fascicularis) CD32b (AAL92097.1) extracellular domain (Met 1-Gly 220) was fused with a C-terminal polyhistidine tagged AVI tag at the C-terminus.

Description

The protein encoded by this gene is a low affinity receptor for the Fc region of immunoglobulin gamma complexes. The encoded protein is involved in the phagocytosis of immune complexes and in the regulation of antibody production by B-cells. Variations in this gene may increase susceptibilty to systemic lupus erythematosus (SLE). Several transcript variants encoding different isoforms have been found for this gene.

Expression System
