表达区间及表达系统（Source） |
Recombinant Human PD-L1/B7-H1 Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Phe19-Arg238.[Uniprot | Q9NZQ7-1] |
|
分子量大小（Molecular Weight） |
The protein has a predicted MW of 52 kDa. Due to glycosylation, the protein migrates to 68-80 kDa based on Tris-Bis PAGE result. |
|
内毒素（Endotoxin） |
Less than 1EU per μg by the LAL method. |
|
纯度（Purity） |
> 95% as determined by Tris-Bis PAG Eand HPLC |
|
活性（Activity） |
ELISA Data: Immobilized Human PD-1, mFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Human PD-L1, hFc Tag with the EC50 of 0.93μg/ml determined by ELISA SPR Data: Human PD-L1, hFc Tag captured on CM5 Chip via Protein A can bind Biotinylated Human PD-1, His-Avi Tag with an affinity constant of 2.356 μM as determined in SPR assay |
|
制剂（Formulation） |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
|
重构方法（Reconstitution） |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
储存条件
