Product Propertie Alternative Names CT22, Sp17-1, Sperm protein 17, SPA17, Species Human Expression Sequence Met1-Lys151 Accession Q15506 Tag N-His Expression System E.coli Molecul ar Weight The protein has a predicted MW of 18.50 kDa. The protein migrates to 20-28 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 20mM Tris, 150mM NaCL (pH 8.0). 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 Lyophilized powder: Store at -25 to -15°C; stable for 1 year upon receipt.Reconstituted protein: Store under sterile conditions at -85 to -65°C; stable for 3 months.
