Gene Information

human ... DEFA6(1671)

General description

The gene DEFA6 (defensin-6) is mapped to human chromosome 8p23.1. It belongs to the defensin family of proteins. DEFA6 is expressed by paneth cells in the intestine.

Immunogen

Defensin-6 Precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-DEFA6 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

DEFA6 (defensin-6) is an antimicrobial peptide, which is mainly involved in intestinal innate immunity. DEFA6-mediated formation of fibrils and nanonets are crucial for enclosing and entraping enteric bacterial pathogens. It is down-regulated in Crohn′s disease (CD). DEFA6 also increases HIV (human immunodeficiency virus) infection by promoting virus attachment on the target cells.

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.
