蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 32.4 kDa. The protein migrates as 55-90 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记（Biotinylation）
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（Biotin: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）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景（Background）
P-selectin glycoprotein ligand 1 (PSGL-1) is also known as Selectin P ligand (SELPLG), CD antigen CD162. PSGL-1 is disulfide-linked homodimer which is the high affinitycounter-receptor for P-selectin on expressed on activated endothelial cells and platelets. PSGL-1 / SELPLG interacts with P-, E- and L-selectins, through their lectin/EGF domains, is required for promoting recruitment and rolling of leukocytes. These interactions require sialyl Lewis X glycan modification but there is a differing dependence for tyrosine sulfations. Dimerization appears not to be required for P-selectin/SELP binding. PSGL-1 can interact with SNX20, MSN and SYK. PSGL-1 / SELPLG mediate the activation of SYK by SELPLG.
