Active Recombinant Human KLK1 protein, His-tagged

• Cat.No.: KLK1-299H
• Product Overview: Recombinant Human KLK1 protein(Met1-Ser262), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-262 aa
• Form: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
• Bio-activity: Measured by its ability to cleave a flourogenic peptide substrate Pro-Phe-Arg-7-amido-4-methylcoumarin (PFR-AMC). The specific activity is >9209 pmol/min/μg.
• Molecular Mass: 29.73 kDa
• Endotoxin: < 0.1 EU/μg of the protein by LAL method.
• Purity: ≥ 95 % as determined by SDS-PAGE.
• Storage: Store at -20°C.Store the lyophilized protein at -20°C to -80°C up to 1 year from the date of receipt.After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C for up to 1 week.
• Reconstitution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.
