表达区间及表达系统（Source） |
Recombinant Human B7-H3/CD276 Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Leu29-Pro245.[Uniprot| Q5ZPR3-2] |
|
分子量大小（Molecular Weight） |
The protein has a predicted MW of 50.1 kDa. Due to glycosylation, the protein migrates to 60-70 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 PAGEand HPLC |
|
活性（Activity） |
ELISA Data:Immobilized Human B7-H3, hFc Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Anti-B7-H3 Antibody, hFc Tag with the EC50 of 42.2ng/ml determined by ELISA. |
|
制剂（Formulation） |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% 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
