Recombinant Human IL-4 R alpha/CD124 Protein,hFc Tag

Description :
Synonyms IL-4R subunit alpha; IL-4 R alpha;CD124; IL-4Ra Source Human IL-4 R alpha/CD124 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Gly24-His232.[Accession | P24394-1] Molecular Weight The protein has a predicted MW of 50.7 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-4, No Tag at 1g/ml (100l/well) on the plate. Dose response curve for Human IL-4 R alpha, hFc Tag with the EC50 of 9.8ng/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.
