Anti-DBI antibody recognises DBI protein

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

Diazepam binding inhibitor (DBI) is an active peptide and exerts many functions in the brain and peripheral tissues. DBI displaces diazepam from benzodiazepine and thereby regulates signal transduction at type A gamma amino butyric acid (GABAA) receptors. DBI is also involved in the synthesis of steroids and neuroactives. DBI regulates glucose stimulated insulin secretion. The levels of DBI in cerebrospinal fluid is associated with depression associated with or without anxiety.


Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

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

Diazepam binding inhibitor (DBI) is a peptide also known as acyl-coenzyme A binding protein. DBI is majorly expressed in the central nervous system. DBI is also expressed in the peripheral tissues, where there is high affinity for benzodiazepine recognition sites. The gene encoding for DBI is localised on human chromosome 2q14.2.
