ARID1A (BAF250A, SWI/SNF Complex, AT-rich Interactive Domain-containing Protein 1A)

ATP-dependent chromatin remodeling complexes play an essential role in the regulation of nuclear processes such as transcription and DNA replication and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits and contains a single molecule of either BRM or BRG1 as the ATPase catalytic subunit. The activity of the ATPase subunit disrupts histone-DNA contacts and changes the accessibility of crucial regulatory elements to the chromatin. The additional core and accessory subunits play a scaffolding role to maintain stability and provide surfaces for interaction with various transcription factors and chromatin (2-5). The interactions between SWI/SNF subunits and transcription factors, such as nuclear receptors, p53, Rb, BRCA1, and MyoD, facilitate recruitment of the complex to target genes for regulation of gene activation, cell growth, cell cycle, and differentiation processes (1,6-9).\nARID1A is one of the accessory subunits of the SWI/SNF complex that is an essential part of the esBAF (mouse embryonic stem cell specific SWI/SNF complex). ARID1A is critical for ES cell pluripotency and differentiation into mesoderm-derived cardiomyocytes and adipocytes (10). In addition, ARID1A has been found to be frequently mutated in several cancers such as uterine and ovarian endometrioid carcinoma and ovarian clear cell carcinoma (11-13).\n\nApplications: \nSuitable for use in Western Blot and Immunohistochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000. Incubate membrane with diluted antibody in 5% w/v BSA, 1X TBS, 0.1% Tween-20 at 4 degrees C with gentle shaking, overnight.\nImmunohistochemistry(Paraffin): 1:500\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
