AT-rich interactive domain-containing protein 1A (ARID1A) is a member of ARID family, which forms a subunit of SWI/SNF (SWItch/Sucrose NonFermentable) chromatin-remodeling complex. It is a tumor suppressor gene, and binds to DNA in a non-sequence specific manner. This gene is located in the chromosomal region 1p36.11. AIRD1A is also called BAF250a, which is one of the two highly conserved isoforms of BAF250/AIRD1. It is a trithorax group (TrxG) protein, and is highly expressed in pre-implantation embryo and embryonic stem (ES) cells.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Anti-ARID1A antibody produced in rabbit has been used in immunohistochemistry.
AT-rich interactive domain 1A (ARID1A) interacts with Brahma-related gene-1 (BRG1) adenosine triphosphate and forms the SWI/SNF complex. It targets the SWI/SNF complex to the specific genes, and helps bind it to the DNA in a sequence non-specific manner. During gastrulation, it plays an essential role in proper germ-layer formation. It also helps maintain the embryonic stem (ES) cell stage and is responsible for the differentiation of cardiomyocytes. Because AIRD1A acts as a tumor suppressor gene, its inactivation has been implicated in various cancers, such as epithelial, ovarian and endometrial carcinomas. It is also linked to gastric cancer and has potential as a marker for the prognosis of patients with early stage gastric cancer.
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.
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
