Data Examples
Immunohistochemistry | BRCA1 in Human Breast Cancer Tissue. BRCA1 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Human BRCA1 Monoclonal Antibody (Catalog # MAB22101) at 5 µg/mL overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # ). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # ) and counterstained with hematoxylin (blue). View our protocol for . |
Immunohistochemistry | BRCA1 in Human Breast. BRCA1 was detected in immersion fixed paraffin-embedded sections of human breast array using Human BRCA1 Monoclonal Antibody (Catalog # MAB22101) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # ) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents. View our protocol for . |
Western Blot | Detection of Human/Mouse BRCA1 by Western Blot. Western blot shows lysates of CH‑1 mouse B cell lymphoma cell line, BaF3 mouse pro-B cell line, U2OS human osteosarcoma cell line and HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Human BRCA1 Monoclonal Antibody (Catalog # MAB22101) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # ). A specific band was detected for BRCA1 at approximately 240 kDa (as indicated). This experiment was conducted under reducing conditions and using . |

Background: BRCA1
The BRCA1 ( BReast CAncer gene 1) tumor suppressor protein has many reported functions. In addition to mediating signal transduction in DNA damage and repair responses, BRCA1 forms a heterodimer with BARD1 and regulates transcriptional activity, assisting in the preservation of chromosomal stability. BRCA1 is one of the first proteins recruited to sites of DNA double-strand breaks and serves as part of a scaffold for assembling other DNA damage response or repair factors, including MSH2, MLH1, ATM and PMS2.
