Product Properties Alternative Names Alpha-fetoprotein, Alpha-1-fetoprotein, Alpha-feto, HPAFP, AFPD, FETA Species Cynomolgus Expression Sequence Arg19-Val609 Accession A0A2K5U7U0 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 67.53 kDa. Due to glycosylation, the protein migrates to 68-75 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 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.
