Product Properties Alternative Names 4F2hc, CD98, SLC3A2, 4F2, CD98HC, MDU1, NACAE, 4T2HC Species Cynomolgus Expression Sequence Arg175-Ala599 Accession XP_045227941.1 Tag N-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 48.02 kDa. Due to glycosylation, the protein migrates to 50-70 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, 200mM L-arginine (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity 【ELISA Data】 Immobilized Cynomolgus CD98, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Anti-CD98 Antibody, hFc Tag with the EC50 of 30.8ng/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.
