Biotinylated Human LILRB1 / CD85j / ILT2 Protein, Fc,Avitag™ (MALS verified)
分子别名(Synonym)
CD85J,LILRB1,CD85,ILT2,LIR1,MIR7
表达区间及表达系统(Source)
Biotinylated Human LILRB1 Protein, Fc,Avitag (CDJ-H82F9) is expressed from human 293 cells (HEK293). It contains AA Ala 23 - Thr 431 (Accession # Q8NHL6-1).
Predicted N-terminus: Ala 23
蛋白结构(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 72.8 kDa. The protein migrates as 90-110 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
纯度(Purity)
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
该基因属于白细胞免疫球蛋白样受体(LIR)家族成员,位于19号染色体q13.4区域的基因簇中。其编码的蛋白质属于LIR受体的B类亚家族,这类受体包含2-4个胞外免疫球蛋白结构域、1个跨膜结构域,以及2-4个胞质内基于酪氨酸的免疫受体抑制基序(ITIMs)。该受体在免疫细胞表面表达,通过与抗原呈递细胞上的MHC I类分子结合,传递抑制信号以阻断免疫反应的激活。其功能被认为是调控炎症反应和细胞毒性作用,从而聚焦免疫应答并限制自身反应性。已发现该基因存在编码不同亚型的多种转录变异体。
