Anti-NPAS2 antibody produced in rabbit，100UL，HPA019674-100UL，Sigma

General description

NPAS2 (Neuronal PAS domain protein 2) is a largest circadian gene encoded helix-loop-helix-PAS class of transcription factor. It is located on chromosome 2q11.2. It is mostly expressed in the mammalian forebrain.

Immunogen

neuronal PAS domain protein 2 recombinant protein epitope signature tag (PrEST)

Application

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

NPAS2 (Neuronal PAS domain protein 2) is a transcription factor highly involved in the regulation of circadian rhythm. Its PAS domains directly bind to the heme as a prosthetic group to control DNA binding in vitro. In the maintenance of circadian behavioral rhythms, NPAS2 heterodimerize with BMAL1, which stimulates transcriptional expression of the circadian genes required for biological rhythms in many organisms.

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.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.
