Product Category Recombinant Protein
Target IL-21R
Synonyms IL-21 receptor; IL-21R; CD360; NILR
Gene/Protein ID NP_068570.1
Species Human
Exact Sequence Cys20-Pro236
Molecular Weight The protein has a predicted MW of 51.8 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.
Activity Immobilized Human IL-21 at 1μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-21R, hFc Tag with the EC50 of 62.4ng/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 IL-21 at 1μg/ml (100μl/Well) on the plate. Dose response curve for Human IL-21R, hFc Tag with the EC50 of 62.4ng/ml determined by ELISA.
The purity of Human IL-21R is greater than 95% as determined by SEC-HPLC.
Human IL-21R on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
