Prostate Specific Antige

Product name:Prostate Specific Antige

Product description:Prostate-specific antigen (PSA) also known as gamma-seminoprotein or kallikrein-3 (KLK3) is a glycoprotein that in humans is encoded by the KLK3 gene. KLK3 is a member of the kallikrein-related peptidase family that are secreted by the epithelial cells of the prostate gland. PSA is produced for the ejaculate where it liquifies the semen in the seminal coagulum and allows sperm to swim freely. It is also believed to be instrumental in dissolving the cervical mucous, allowing the entry of sperm.
