ANTI-HIF1A (C15-1445-229)

General description

The gene encoding HIF1A (hypoxia inducible factor 1 subunit α) is localized on human chromosome 14q23.2. It is part of the HIF-1 heterodimer complex and is modulated by oxygen.

Immunogen

Hypoxia-inducible factor 1 α 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.

Rabbit polyclonal anti-HIF1A antibody is used to tag hypoxia-inducible factor 1 α for detection and quantitation by immunocytochemical and immunohistochemical (IHC) techniques such as immunoblotting, immunoprecipitation, and immunofluorescence. It is used as a probe to determine the presence and roles of hypoxia-inducible factor 1 α in the structure and function of hypoxia-inducible factor 1.

Biochem/physiol Actions

Hypoxia-inducible factor 1, α subunit (HIF1A) combines with aryl hydrocarbon receptor nuclear translocator (Arnt, HIF1B), the β subunit to create the heterodimeric basic helix-loop-helix transcription factor hypoxia-inducible factor 1. Many hypoxia-regulated genes are mediated by the hypoxia-inducible factor 1 (HIF-1) complex. HIF-1 binds to the promoter of hypoxia-responsive genes and other transcription factors, such as p300, signal and transducer of transcription 3, and redox effector factor 1/apurinic/apyrimidinic endonuclease.

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.

Linkage

Corresponding Antigen APREST70506.

Physical form

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