Anti-Human Hepsin (Clone 2D5) – Purified in vivo PLATINUM™ Functional Grade

Human hepsin protein

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.

Functional grade preclinical antibodies are manufactured in an animal free facility using in vitro cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.

To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco’s Purified Functional PLATINUM™ antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.

Functional grade preclinical antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C. Avoid Repeated Freeze Thaw Cycles.

Next Day 2-8°C

Clone 2D5 recognizes Human hepsin. It binds to a separate epitope than clone 3H10.1. These clones do not interfere with one another.

Hepsin is a type II transmembrane serine protease (TTSP) expressed on the surface of epithelial cells including the liver, kidney, prostate, and thyroid in human tissues. The physiological function of hepsin is unclear, although, In vitro studies have shown that hepsin activates blood clotting factors VII, XII, and IX, pro-urokinase (pro-uPA), and pro-hepatocyte growth factor (pro-HGF). The over-expression of hepsin has been implicated in several types of cancer, especially ovarian and prostate, which makes it an attractive diagnostic marker for cancers. Most notably, hepsin has been identified as one of the most highly induced genes in prostate cancer, and this over-expression is correlated with the cancer progression and metastasis. Furthermore anti-hepsin antibodies have been shown to inhibit the invasion of human prostate cancer cells.¹
