INTRODUCTION
FCGR3B, also known as CD16b belongs to the Ig super family. FCGR3B encodes a glycosylphosphatidylinositol (GPI)-anchored protein which is expressed constitutively by neutrophils. FCGR3B binds to complex or aggregated IgG and monomeric IgG. Different from III-A, FCGR3B cannot arbitrate antibody-dependent cytotoxicity and phagocytosis. FCGR3B operate to capture immune complexes in peripheral blood circulation that does not activate neutrophils.
DESCRIPTION
FCGR3B produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 188 amino acids (21-200a.a.) and having a molecular mass of 21.4kDa. (Molecular size on SDS-PAGE will appear at approximately 28-40kDa).
FCGR3B is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
SOURCE
Sf9, Baculovirus cells.
PHYSICAL APPEARANCE
Sterile filtered colorless solution.
FORMULATION
FCGR3B protein solution (0.25mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
STABILITY
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
PURITY
Greater than 90.0% as determined by SDS-PAGE.
