Recombinant Human FCGR3B Protein, His-tagged

• Cat.No.: FCGR3B-226H
• Product Overview: Recombinant Human FCGR3B(21-200aa) fused with His tag at C-terminal was expressed in Insect cells.

Specification

• Species: Human
• Source: Insect Cells
• Tag: His
• Protein Length: 21-200aa
• Description: FCGR3B, also known as low affinity immunoglobulin gamma Fc region receptor III-B isoform 2, is a member of Ig super family. It encodes a glycosylphosphatidylinositol (GPI)-anchored protein that is expressed constitutively by neutrophils and after gamma-interferon stimulation by eosinophils. This protein binds to complex or aggregated IgG and monomeric IgG. Unlike III-A, it cannot mediate antibody-dependent cytotoxicity and phagocytosis. It can be a trap of immune complexes in peripheral blood circulation that does not activate neutrophils.
• Form: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol.
• Molecular Mass: 21.4kDa (188aa) 28-40kDa (SDS-PAGE under reducing conditions)
