Recombinant Human PSA/KLK3 Protein (His Tag)

Product Specifications

Background

KLK3 (Kallikrein 3) ; also known as Prostate Specific Antigen (PSA) ; kallikrein-related peptidase 3; Gamma-seminoprotein; is a secreted protein of the glandular kallikrein subfamily of serine proteases.KLK3 contains one peptidase S1 domain.KLK3 is a glycoprotein produced almost exclusively by the prostate gland. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers.
