Molecular Weight | The protein has a predicted MW of 83.8 kDa. Due to glycosylation, the protein migrates to 110-135 kDa based on Tris-Bis PAGE result. |
Activity | Immobilized Human IL-31, His Tag at 5μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-31 RA, hFc Tag with the EC50 of 1.2μg/ml determined by ELISA. The affinity constant of 1.5nM as determined in SPR assay (Biacore T200). 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. |
