Recombinant Rat IL-13Ra2 Protein,His Tag

Description :
Synonyms CD213a2; IL-13 R alpha 2; IL13BP; IL13R; IL13RA2; IL-13R subunit alpha-2; IL-13Ra2 Source Rat IL-13Ra2 Protein is expressed from HEK293 with His tag at the C-terminus. It contains Leu24-Lys336.[Accession | Q8VHK6] Molecular Weight The protein has a predicted MW of 37.51 kDa. Due to glycosylation, the protein migrates to 48-58 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 Rat IL-13Ra2, His Tag at 0.5g/ml (100l/well) on the plate. Dose response curve for Human IL-13, hFc Tag with the EC50 of 11.7ng/ml determined by ELISA. Formulation Lyophilized from 0.22 m 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.
