Molecular Weight The protein has a predicted MW of 39.8 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result.
Activity Immobilized Human SIRP alpha V4, His Tag at 1μg/ml (100μl/Well).Dose response curve for Human CD47, hFc Tag with the EC50 of 56.8ng/ml determined by ELISA. See testing image for detail.
Product Tag C-His-Avi
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 SIRP alpha V4, His Tag at 1μg/ml (100μl/Well).Dose response curve for Human CD47, hFc Tag with the EC50 of 56.8ng/ml determined by ELISA.
The purity of Human SIRP alpha V4 is greater than 95% as determined by SEC-HPLC.
