Anti-PKK antibodies enable researchers to detect and measure the PKK antigen in biological samples. This target is a reported synonym of the KLKB1 gene, which encodes kallikrein B1. This protein is known to function in proteolysis, among other biological roles. The human version of PKK has a canonical amino acid length of 638 residues and a protein mass of 71.4 kilodaltons. It is reported to be a secreted protein. This target antigen may also be known as KLK3. Indicated applications for PKK antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
