Kallikrein hK2 is a new potential marker of prostate cancer. It is the last member of the human kallikrein gene family to be isolated. We propose a simple purification procedure permitting us to obtain the active form of hK2 starting from human seminal plasma and using commonly available chromatography matrices. In contrast to recently published papers, this procedure is carried out without any immunoaffinity chromatography step and without the need for any antibody to follow the purification. Furthermore, it does not require any recombinant DNA technology nor sophisticated instruments.

UI MeSH Term Description Entries
D007610 Kallikreins Proteolytic enzymes from the serine endopeptidase family found in normal blood and urine. Specifically, Kallikreins are potent vasodilators and hypotensives and increase vascular permeability and affect smooth muscle. They act as infertility agents in men. Three forms are recognized, PLASMA KALLIKREIN (EC 3.4.21.34), TISSUE KALLIKREIN (EC 3.4.21.35), and PROSTATE-SPECIFIC ANTIGEN (EC 3.4.21.77).
