分子別名(Synonym)
FCGR1A,FCG1,FCGR1,IGFR1,CD64,CD64A,FCRI
表達區(qū)間及表達系統(tǒng)(Source)
Human CD64, His Tag (FCA-H52H1) is expressed from human 293 cells (HEK293). It contains AA Gln 16 - Leu 281 (Accession # P12314-1).
Predicted N-terminus: Gln 16
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 31.8 kDa. The protein migrates as 45-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)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 with trehalose as protectant.

背景(Background)
識別IgG Fc部分的受體分為三組,分別稱為Fcγ-RI、RII和RIII,也分別稱為CD64、CD32和CD16。Fc-gamma RI以高親和力結(jié)合IgG,并在早期免疫反應(yīng)中發(fā)揮作用。Fc-gamma RII和RIII是低親和力受體,在晚期免疫應(yīng)答期間將IgG識別為多價抗原周圍的聚集體。
高親和力免疫球蛋白γ-Fc受體I也稱為FCGR1A、FCG1、FCGR1、CD64和IGFR1,是一種以高親和力結(jié)合單體IgG型抗體的完整膜糖蛋白,屬于免疫球蛋白超家族或FCGR1家族。FCGR1A/CD64含有3個Ig樣C2型(免疫球蛋白樣)結(jié)構(gòu)域。CD64僅在巨噬細胞和單核細胞上存在,但用IFNγ和G-CSF等細胞因子處理多形核白細胞可以誘導CD64在這些細胞上表達。
