Application Note
For IHC-P: Use at an assay dependent dilution. Perform heat mediated antigen retrieval before commencing with IHC staining protocol (0.1 M citrate buffer at 95C in water bath for 20 min). Avoid nonspecific binding by incubating in normal rabbit anti-mouse serum. Incubate primary antibody overnight and use a biotin-streptavidin amplification kit. Block endogenous peroxidase with 0.3% H2O2 for 30 minutes. For IP: Use at an assay dependent dilution. For WB: 1:500-1:3000. This antibody recognizes full-length BRCA1, a 220-kDa nuclear phosphoprotein. Optimal dilutions/concentrations should be determined by the researcher.

Background
This gene encodes a nuclear phosphoprotein that plays a role in maintaining genomic stability, and it also acts as a tumor suppressor. The encoded protein combines with other tumor suppressors, DNA damage sensors, and signal transducers to form a large multi-subunit protein complex known as the BRCA1-associated genome surveillance complex (BASC). This gene product associates with RNA polymerase II, and through the C-terminal domain, also interacts with histone deacetylase complexes. This protein thus plays a role in transcription, DNA repair of double-stranded breaks, and recombination. Mutations in this gene are responsible for approximately 40% of inherited breast cancers and more than 80% of inherited breast and ovarian cancers. Alternative splicing plays a role in modulating the subcellular localization and physiological function of this gene. Many alternatively spliced transcript variants, some of which are disease-associated mutations, have been described for this gene, but the full-length natures of only some of these variants has been described. A related pseudogene, which is also located on chromosome 17, has been identified. [provided by RefSeq, May 2009]
