表达区间及表达系统（Source） |
Recombinant Human SIRP alpha/CD172a Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Glu31-Arg370. Uniprot | P78324-1 |
|
分子量大小 （Molecular Weight） |
The protein has a predicted MW of 64.1 kDa. Due to glycosylation, the protein migrates to 78-90 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 SEC-HPLC |
|
活性（Activity） |
ELISA Data :Immobilized Human CD47, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Human SIRP alpha, hFc Tag with the EC50 of 46.8ng/ml determined by ELISA. ELISA Data: Immobilized Human SIRP alpha, hFc Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Anti-SIRP alpha Antibody, hFc Tag with the EC50 of 26.9ng/ml determined by ELISA. |
|
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. |
