Product Properties Alternative Names IL12R,CD212,IL-12RB1,IL-12R-beta-1 Species Human Expression Sequence Cys24-Glu540 Accession P42701-1 Tag C-hFc Expression System HEK293 Molecular Weight The protein has a predicted MW of 83.85 kDa. Due to glycosylation, the protein migrates to 95-115 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 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity 【ELISA Data】 Immobilized Human IL-12B, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for Human IL-12 R beta 1, hFc Tag with the EC50 of 0.26μg/ml determined by ELISA. 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 -85 ~ -65℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃ under sterile conditions, valid for 3 months.
