Scientific Data Images for Human Hepsin Antibody
Hepsin in Human Liver.
Hepsin was detected in immersion fixed paraffin-embedded sections of human liver using Mouse Anti-Human Hepsin Monoclonal Antibody (Catalog # MAB47761) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of hepatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.Applications for Human Hepsin Antibody

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; most 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 over-expressed in various human tumors including prostate (5) and is considered to be a biomarker for prostate cancer (6). Recombinant human (rh) Hepsin was expressed as a secreted, soluble protein lacking its cytosolic and transmembrane domains. The D161E and R162K mutations were introduced into the prosequence to improve expression of the rhHepsin.
