Description

Recombinant Protein

It is recommended that the protein be aliquoted for optimal storage. It is recommended that sterile water (250 μL) be added to the vial to prepare a stock solution of 0.2 mg/mL. Concentration is measured by UV.

Hippostasin, also known as KLK11, is a kallikrein-like serine protease, which has two alternatively spliced isoforms, brain-type and prostate-type. Hippostasin plays a role in the prostate, including reproductive and/or tumorigenic functions. Elevated serum levels of KLK11 were found in 70% of women with ovarian cancer and in 60% of men with prostate cancer. Analysis of the KLK11 biomarker in serum may aid in the diagnosis and monitoring of ovarian and prostatic carcinoma.
