Mouse Fc gamma RIV / CD16-2 Protein, His Tag (MALS verified)
分子別名（Synonym）
Fc gamma RIV,CD16-2,Fcgr4,FCGR4,mouse igg,Fc receptor
表達區(qū)間及表達系統(tǒng)（Source）
Mouse CD16-2, His Tag (FC4-M52H3) is expressed from human 293 cells (HEK293). It contains AA Gly 21 - Gln 203 (Accession # A0A0B4J1G0-1).
Predicted N-terminus: Gly 21
蛋白結構（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 22.8 kDa. The protein migrates as 28-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
純度（Purity）
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景（Background）
FcgR4（低親和力免疫球蛋白γFc區(qū)受體IV）也稱為CD16-2、FcgammaRIV，是免疫球蛋白βFc區(qū)的受體。還充當免疫球蛋白εFc區(qū)的受體。以中等親和力結合IgG2a和IgG2b。不顯示與IgG1或IgG3的結合。通過增強與IgG2a結合后的破骨細胞分化，在促進骨吸收方面發(fā)揮作用。與IgE的a和b同種異型結合的親和力較低。也已被證明僅與IgE同種異型a結合，而不與同種異型b結合。與IgE結合可促進巨噬細胞介導的吞噬作用、T細胞的抗原呈遞、促炎細胞因子的產生和皮膚過敏反應的晚期。
