Recombinant Biotinylated Human IL-13 Protein,His-Avi Tag

Description :
Synonyms interleukin 13; IL-13;IL13; P600 Source Biotinylated Human IL-13 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Gly21-Asn132.[Accession | AAK53823] Molecular Weight The protein has a predicted MW of 15.3 kDa. Due to glycosylation, the protein migrates to 15 kDa and 35-45 kDa based on SDS-PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 90% as determined by SDS-PAGE Activity ELISA Data: Immobilized Biotinylated Human IL-13, His Tag at 2g/ml (100l/Well) on streptavidin (5g/ml) precoated plate. Dose response curve for Human IL-13Ra2, hFc Tag with the EC50 of 1.15g/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.
