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

Description :
Synonyms CD218a; IL1RRP; IL18R1; IL-1 Rrp Source Human IL-18 R1/CD218a Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. 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 SDS-PAGE and HPLC. Activity SPR Data: Human IL-18 R1, His Tag captured on CM5 Chip via anti-his antibody can bind Human IL-18, No Tag with an affinity constant of 2.38 nM 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 the tube before opening. Reconstituting to a concentration more than 100 g/ml is recommended. Dissolve the lyophilized protein in distilled water.
