Product Properties Alternative Names CA125, CA-125, CA125MUC-16, FLJ14303, MUC16 Species Human Expression Sequence Asp12783-Ser13467 Accession Q8WXI7 Tag C-His-Avi Expression System HEK293 Molecular Weight The protein has a predicted MW of 77.98 kDa. Due to glycosylation, the protein migrates to 90-140 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE. 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 【ELISA Data】 Immobilized Human MSLN, hFc Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Biotinylated Human CA125, His Tag with the EC50 of 16.5ng/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 -25 ~ -15℃, valid for 1 year after receipt. After reconstitution, store at -85 ~ -65℃ under sterile conditions, valid for 3 months.
