Product Properties Alternative Names PLAU, Urokinase, ATF, UPA, URK, u-PA, BDPLT5, QPD Species Rat Expression Sequence Gly20-Phe432 Accession NP_037217.3 Tag C-His Expression System HEK293 Molecular Weight The protein has a predicted MW of 46.91 kDa. The protein migrates to 30-35 kDa based on SDS-PAGE result. Purity > 95% as determined by SDS-PAGE,> 90% as determined by HPLC Endotoxin < 1.0 EU per μg by the LAL method. Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. Appearance Lyophilized Powder Biological Activity 【SPR Data】Human uPAR, hFc Tag captured on CM5 Chip via Protein A can bind Rat PLAU, His Tag with an affinity constant of 4.31 μM as determined in SPR assay . 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.
