Molecular Weight The protein has a predicted MW of 63.9 kDa. Due to glycosylation, the protein migrates to 75-85 kDa based on Tris-Bis PAGE result.
Activity Immobilized Human CD47 at 1μg/ml (100μl/Well). Dose response curve for Human SIRP alpha V2, hFc Tag with the EC50 of 82.3ng/ml determined by ELISA. See testing image for detail.
Product Tag C-hFc
Express System Expi293
Purity > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC
Endotoxin Less than 1EU per μg by the LAL method.
Form Lyophilized
Shipping Shipped at ambient temperature.
Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5 % trehalose is added as protectant before lyophilization.
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.
Stability And Storage Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
Immobilized Human CD47 at 1μg/ml (100μl/Well). Dose response curve for Human SIRP alpha V2, hFc Tag with the EC50 of 82.3ng/ml determined by ELISA.
The purity of Human SIRP alpha V2/CD172a is greater than 95% as determined by SEC-HPLC.
