Datasheets
  • BRCA1 Antibody (D-9) is a mouse monoclonal IgG2a κ BRCA1 antibody, cited in 454 publications, provided at 200 µg/ml
  • specific for an epitope mapping between amino acids 1843-1862 at the C-terminus of BRCA1 of human origin
  • BRCA1 Antibody (D-9) is recommended for detection of BRCA1 of human origin by WB, IP, IF and ELISA
  • Anti-BRCA1 Antibody (D-9) is available conjugated to agarose for IP; HRP for WB, IHC(P) and ELISA; and to either phycoerythrin or FITC for IF, IHC(P) and FCM
  • also available conjugated to Alexa Fluor® 488, Alexa Fluor® 546, Alexa Fluor® 594 or Alexa Fluor® 647 for WB (RGB), IF, IHC(P) and FCM, and for use with RGB fluorescent imaging systems, such as iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • also available conjugated to Alexa Fluor® 680 or Alexa Fluor® 790 for WB (NIR), IF and FCM; for use with Near-Infrared (NIR) detection systems, such as LI-COR®Odyssey®, iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • m-IgG Fc BP-HRP, m-IgG2a BP-HRP and m-IgGκ BP-HRP are the preferred secondary detection reagents for BRCA1 Antibody (D-9) for WB applications. These reagents are now offered in bundles with BRCA1 Antibody (D-9) (see ordering information below).

BRCA1 Antibody (D-9) is a mouse monoclonal IgG2a kappa light chain antibody that detects BRCA1 of human origin by western blotting, immunoprecipitation, immunofluorescence, and enzyme-linked immunosorbent assay. BRCA1 (D-9) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase, phycoerythrin, fluorescein isothiocyanate, and multiple Alexa Fluor® conjugates. BRCA1, identified in 1990 and localized to chromosome 17q, plays a crucial role in maintaining genomic stability and is essential for DNA repair processes. BRCA1 mutations are linked to approximately 45% of families with a high incidence of breast cancer and at least 80% of families with increased rates of both early-onset breast cancer and ovarian cancer. Unlike BRCA2, which is located on chromosome 13q13.1, BRCA1 is a significant tumor suppressor that negatively regulates tumor growth, making BRCA1 vital in cancer prevention. BRCA1, consisting of 1863 amino acids, features a zinc finger domain in its amino terminal region, which is critical for interaction with other proteins involved in DNA repair and cell cycle regulation. BRCA1 (D-9) monoclonal antibody can provide valuable insights into mechanisms of breast and ovarian cancer, as well as broader implications of BRCA1 in tumor biology.
