Programmed Death-1 receptor, also known as PD-1 and CD279, is a receptor expressed on T cells responsible for modulating T cell activation. Like CTLA4, PD-1 is classified as an immune checkpoint inhibitory receptor. Mature human PD-1 consists of an extracellular region (ECD) with one immunoglobulin-like Vtype domain, a transmembrane domain, and a cytoplasmic region. The mature ECD of human PD-1 shares 61% amino acid sequence identity with mouse PD-1 ECD.

表达区间及表达系统(Source) |
HEK293 Cells-derived Human PD-1 / PDCD1 Protein, Leu25-Gln167 with His tag at the C-terminal |
分子量(Molecular Weight) |
Approximately 17.0 kDa. Due to glycosylation, the protein migrates to 38-50 kDa based on Tris-Bis PAGE result. |
外观(Physical Appearance) |
Sterile Filtered White lyophilized (freeze-dried) powder. |
纯度(Purity) |
> 95% as determined by SDS-PAGE and HPLC |
活性(Activity) |
ELISA Data: Immobilized Human PD-1, His Tag at 0.5 μg/mL (100 μL/Well). Dose response curve for Anti-PD-1 Antibody, hFc Tag with the EC50 of 45.0 ng/mL determined by ELISA. |
内毒素(Endotoxin) |
< 1.0 EU per 1μg of the protein by the LAL method. |
制剂(Formulation) |
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
复溶(Reconstitution) |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended (usually we use 1mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
运输与保存方法
