Product Properties Alternative Names CD8 alphaβ CD8A&CD8B Species Mouse Expression Sequence Lys28-Tyr196(CD8 alpha) acidic tail and Leu22-Thr175(CD8 beta) basic tail Accession P017 31(CD8 alpha)&P10300(CD8 beta) Tag C-His-Flag Expression System HEK293 Molecular Weight The protein has a predicted MW of 24.80 kDa (CD8 alpha) and 23.17 kDa (CD8 beta). Due to glycosylation, the protein migrates to 32-38 kDa (CD8 alpha) and 42-50 kDa (CD8 beta) 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 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
