Kallikrein 1, Human

Synonyms KLK1
Description Kallikrein 1 (KLK1), also known as tissue kallikrein, is a member of the human tissue kallikrein family. Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis, and some have the potential to be used as cancer and other disease biomarkers. Human KLK1 precursor contains a signal peptide (residues 1 to 18), a short pro peptide (residues 19 to 24) and a mature chain (residues 25 to 262).
Recombinant Human Kallikrein 1 produced in CHO cells is a polypeptide chain containing 292 amino acids. A fully biologically active molecule, rhKLK1 has a molecular mass of 46 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
Accession No P06870
Source CHO
Biological Activity The Specific Activity is > 1500 pmol/min/μg, Measured by hKLK1’s ability to cleave the fluorogenic peptide substrate Pro-Phe-Arg-AMC (Bachem, I-1295)
Activation Buffer:50 mM Tris, 10 mM CaCl2, 150 mM NaCl, pH 7.5
Assay Buffer: 50m M CHES, 250m M NaCl, pH 10.0
Activate hKLK1:
Dilute hKLK1 to 200 ug/ml in Activation Buffer;
Dilute Thermolysin to 2μg/mL in Activation Buffer;
Combine equal volumes of 200 ug/ml hKLK1 and 2 ug/ml Thermolysin;
Incubate at 37 °C for 1 hour.
