Kallikrein-Related Peptidase 7 (KLK7), recombinant human protein is supplied as a lyophilized powder. It is suitable for use in protein studies such as enzymetic analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the human KLK7 (NP_005037.1) extracellular domain (Met 1-Arg 253) fused to a C-terminal polyhistidine tag.

Activity: Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK (Dnp) NH₂, R&D Systems, Catalog # ES002. The specific activity is >150 pmoles/min/µg.

Formulation: Lyophilized in 140 mM NaCl, 2.7 mM KCl, 10 mM Na₂HPO₄, 1.8 mM KH₂PO₄, pH7.4, 5% Mannitol, 5% Trehalose, 0.02% Tween80.

Reconstitution: Dissolve the protein in sterile double distilled water to a concentration of 25 µg/µl or lower. It is recommended that the protein be aliquoted and be used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
