Molecular Weight The protein has a predicted MW of 24.7 kDa. Due to glycosylation, the protein migrates to 45-70 kDa based on Tris-Bis PAGE result.
Activity Immobilized Human IL-4 R alpha, His Tag at 1μg/ml (100μl/Well). Dose response curve for Biotinylated Human IL-4, His Tag with the EC50 of 11.76ng/ml determined by ELISA. See testing image for detail.
Product Tag C-His
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 IL-4 R alpha, His Tag at 1μg/ml (100μl/Well). Dose response curve for Biotinylated Human IL-4, His Tag with the EC50 of 11.76ng/ml determined by ELISA.
