Fc gamma RIIIB/CD16b 蛋白, Human (Biotinylated, NA2)

Fc gamma RIIIB/CD16b Protein, a low-affinity receptor for IgG, binds complexed or monomeric IgG. Unlike Fc gamma RIIIA, it cannot mediate antibody-dependent cytotoxicity or phagocytosis. Instead, Fc gamma RIIIB may act as a trap for immune complexes, circulating without activating neutrophils. Existing as a monomer, it interacts with INPP5D/SHIP1, implying its role in intracellular signaling pathways linked to immune responses. Fc gamma RIIIB/CD16b Protein, Human (Biotinylated, NA2) is the recombinant human-derived Fc gamma RIIIB/CD16b protein, expressed by E. coli , with tag free.

Fc gamma RIIIB/CD16b 蛋白充当免疫球蛋白 gamma Fc 区的受体，表现出低亲和力并与复合或聚集的 IgG 以及单体 IgG 结合。与 Fc γ RIIIA 相比，Fc γ RIIIB 缺乏介导抗体依赖性细胞毒性和吞噬作用的能力。相反，它可能充当外周循环免疫复合物的陷阱，而不激活中性粒细胞。该蛋白以单体形式存在，并与 INPP5D/SHIP1 相互作用，表明其参与与免疫反应相关的细胞内信号传导途径。

Approximately 20 kDa

Greater than 90% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
