Product Properties Alternative Names Pkm, Pk3, Pykm, Pk-2, Pk-3 Species Mouse Expression Sequence Pro2-Pro531 Accession NP_001240812.1 Tag N-His Expression System Baculovirus-Insect Cells Molecular Weight The protein has a predicted MW of 58.95 kDa same as 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, 500mM NaCl (pH 7.0). 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 Store at -25 to -15°C. The shelf life is 1 year from the date of receipt. After reconstitution, store at -85 to -65°C under sterile conditions for up to 3 months.
