Biotinylated Human LILRB2 / CD85d / ILT4 Protein, Fc,Avitag? (MALS verified)

分子別名（Synonym）

LILRB2,ILT4,LIR2,MIR10,CD85d

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Biotinylated Human LILRB2, Fc,Avitag (LI2-H82F5) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Val 461 (Accession # AAH36827.1).

Predicted N-terminus: Gln 22

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag?).

The protein has a calculated MW of 76.2 kDa. The protein migrates as 90-110 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

標(biāo)記（Labeling）

Biotinylation of this product is performed using Avitag? technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白標(biāo)記度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

背景（Background）

白細(xì)胞免疫球蛋白樣受體亞家族B成員2（LILRB2）也稱為CD85抗原樣家族成員D（CD85d）、免疫球蛋白類轉(zhuǎn)錄物4（ILT-4）、單核細(xì)胞/巨噬細(xì)胞免疫球蛋白狀受體10（MIR-10），它是LIR受體亞家族的B類成員。LILRB2是I類MHC抗原的受體。LILRB2識別廣泛的HLA-a、HLA-B、HLA-C和HLA-G等位基因。LILRB2與CD8A競爭結(jié)合I類MHC抗原。LILRB2/CD85d抑制FCGR1A介導(dǎo)的細(xì)胞蛋白磷酸化和細(xì)胞內(nèi)鈣離子的動員。
