Recombinant Cynomolgus IFN alpha/beta R2 Protein,His Tag

Description :
Synonyms IFN-R-2; IFNAR2; IFNARB; IFNABR; IFN-alpha; IFN-alpha/beta R2; IFNbR2; IFN-R; receptor 2; receptor10; Source Cynomolgus IFN alpha/beta R2 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ile27-Lys243.[Accession | EHH53981.1] Molecular Weight The protein has a predicted MW of 25.93 kDa. Due to glycosylation, the protein migrates to 43-60 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 IFN alpha/beta R2, His Tag captured on CM5 Chip via anti-his antibody can bind Human IFN alpha 1, hFc Tag with an affinity constant of 70.28 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.
