表达区间及表达系统（Source）

Biotinylated Human IL-3 R alpha, Fc,Avitag (ILA-H82F3) is expressed from human 293 cells (HEK293). It contains AA Thr 19 - Arg 305  (Accession # P26951-1).

Predicted N-terminus: Thr 19 

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 61.2 kDa. The protein migrates as 80-100 kDa 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.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.

背景（Background）

白细胞介素3受体α（低亲和力）（IL-3RA），也称为CD123（分化簇123），是造血素受体超家族的70kD糖蛋白成员。这种蛋白质与IL-5和粒细胞巨噬细胞集落刺激因子（GM-CSF）受体共有的β亚基结合，形成IL-3的高亲和力受体。白细胞介素-3受体α链（CD123）已被确定为潜在的免疫治疗靶点，因为与正常造血干细胞相比，它在AML中过表达。
