Product Properties Alternative Names IFN-R-2, IFNAR2, IFNARB, IFNABR, IFN-alpha, IFN-alpha,beta R2, IFNbR2, IFN-R, β receptor 2, β receptor10, Species Cynomolgus Expression Sequenc e Ile27-Lys243 Accession EHH53981.1 Tag C-His Expression System HEK293 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. Purity > 95% as determined by SDS-PAGE and HPLC. Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological 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 . Reconstitution Method Before opening, centrifuge briefly. Reconstitute the lyophilized protein with distilled water to a concentration exceeding 100 μg/mL. Aliquot after initial reconstitution to avoid repeated freeze-thaw cycles. Features High purity, high activity, low endotoxin, high batch-to-batch consistency Storage Store at -25 to -15°C. Once received, the product is valid for one year. After reconstitution, store under sterile conditions at -85 to -65°C. The product is valid for three months. Show more
