Fc gamma RIIIB/CD16b (NA2) Protein, Human, Recombinant (His & Avi)

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. Fc gamma RIIIB/CD16b (NA2) Protein, Human, Recombinant (His & Avi) is expressed in HEK293 mammalian cells with C-His-Avi tag. The predicted molecular weight is 23.7 kDa and the accession number is O75015-1.

Description

Species	Human
Expression System	HEK293 Cells
Tag	C-His-Avi
Accession Number	O75015-1
Synonyms	FCGR3, FCGR3B, CD16B, Fc γ RIIIB/CD16b (NA2), CD16b (NA2), IGFR3, FCG3, FcgRIIIB, Fc gamma RIIIB, FCRIIIB, FCR-10, Fc γ RIIIB, FCG3B, CD16
Construction	Gly17-Ser200(NA2). The CD16b NA1 differ with the CD16b NA2 in AA36, 65, 82, and 106.The CD16b NA1 form carries R36, N65, D82, and V106, while the CD16b NA2 form carries S36,S65, N82, and I106.
Protein Purity	> 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Molecular Weight	23.7 kDa (predicted). Due to glycosylation, the protein migrates to 47-53 kDa based on Tris-Bis PAGE result.

Endotoxin	< 1 EU/μg by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.
Stability & Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at-80℃. For reconstituted proteinsolutions, the solution can be stored at -20°c to -80'c for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
Shipping	In general, Lyophilized powders are shipping with blue ice.
