Recombinant Cynomolgus IL-18 R1/CD218a Protein,His Tag

Description :
Synonyms CD218a; IL18Ra; IL18R1; IL1RRP; IL-1 R5; IL-1 Rrp; IL-18 R alpha; IL-18 R1; IL-18Ra Source Cynomolgus IL-18 R1/CD218a Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Cys22-Gly329.[Accession | A0A2K5V3J9] Molecular Weight The protein has a predicted MW of 36.45 kDa. Due to glycosylation, the protein migrates to 60-70 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:Cynomolgus 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 2.02 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.
