Recombinant Human IL-1R1 Protein

Description :
Synonyms IL-1R-alpha;IL-1 RI;IL-1RT1;IL-1R-1 Source Human IL-1R1 Protein is expressed from HEK293 without tag. It contains Leu18-Thr332.[Accession | NP_000868.1] Molecular Weight The protein has a predicted MW of 36.17 kDa. Due to glycosylation, the protein migrates to 50-65 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 SPR Data:Human IL-1 Beta, His Tag captured on CM5 Chip via Anti-his antibody can bind Human IL-1R1, No Tag with an affinity constant of 11.37 nM as determined in SPR assay . 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.
