Application

Anti-HPGD antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

15-hydroxyprostaglandin dehydrogenase (HPGD) has a functional colon cancer tumor suppressor activity. This enzyme catalyzes the inactivating NAD⁺-dependent conversion of the prostaglandin 15-OH group to a 15-keto group. Its expression is directly controlled and strongly induced by activation of the TGF-β tumor suppressor pathway. The enzymatic pathway that induces colon cancer suppression is activated by TGF-β and mediated by HPGD. It also catalyzes the NAD-dependent dehydrogenation of lipoxin A4 (LXA4) to form 15-oxo-lipoxin A4 by the dehydrogenation of the C15 hydroxyl group of LXA4 to an oxo- group hence forming 15-oxo-LXA4. Mutations in this gene can cause primary hypertrophic osteoarthropathy and cranioosteoarthropathy.

Features and Benefits

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.Every Prestige Antibody is tested in the following ways: IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. Protein array of 364 human recombinant protein fragments.

General description

15-hydroxyprostaglandin dehydrogenase (HPGD) is a prostaglandin-degrading enzyme and belongs to the short chain dehydrogenases/reductase family. The gene HPGD is mapped to human chromosome 4.
