Scientific Data Images for Human Hepsin Antibody

Detection of Human Hepsin antibody by Western Blot.

Detection of Human Hepsin by Western Blot.

Western blot shows lysates of human prostate tissue, human liver tissue, LNCaP human prostate cancer cell line, and PC-3 human prostate cancer cell line. PVDF membrane was probed with 2 µg/mL of Sheep Anti-Human Hepsin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4776) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Hepsin at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 7.

Background: Hepsin

Hepsin, also known as TMPRSS1, is a Type II membrane protein with an extracellular serine protease domain (1). It is most highly expressed in liver, but is also present in many other tissues, notably lung, kidney, and skeletal muscle (2). A soluble form of Hepsin lacking the transmembrane domain has been identified (3). Hepsin is capable of activating Factor VII, and may initiate blood coagulation at the cell surface (4). Hepsin is overexpressed in various human tumors, including prostate (5), and is considered to be a biomarker for prostate cancer (6).
