Recombinant Biotinylated Human IL-18 R1/CD218a Protein,His-Avi Tag

Description :
Source Biotinylated Human IL-18 R1/CD218a Protein is expressed from HEK293 with His tag and Avi tag at the C-terminal. It contains Ala19-Arg329.[Accession |AAH69575] Molecular Weight The protein has a predicted MW of 38.8 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result. 内毒素Endotoxin Less than 1EU per g by the LAL method. Purity > 95% as determined by Tris-Bis PAGEandHPLC Activity SPR Data: Biotinylated Human IL-18 R1, His Tag captured on CM5-SA Chip can bind Human IL-18, No Tag with an affinity constant of 1.4nM as determined in SPR assay Formulation Lyophilized from 0.22m filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
