Recombinant Human IL-15RA/IL-15 R alpha/CD215 Protein,hFc Tag

Description :
Synonyms IL-15RA; CD215;IL-15 R alpha; Source Human IL-15RA/IL-15 R alpha/CD215 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Ile31-Thr205.[Accession | Q13261-1] Molecular Weight The protein has a predicted MW of 45.1 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by SDS-PAGE and HPLC. Activity ELISA Data: Immobilized Human IL-15, No Tag at 0.5g/ml (100l/Well) on the plate. Dose response curve for Human IL-15RA, hFc Tag with the EC50 of 30.2ng/ml determined by ELISA. Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
