Detection of HER2 in Human Breast Cancer via Multiplex Immunofluorescence staining on COMET™​

HER2 was detected in immersion fixed paraffin-embedded sections of human breast cancer using Mouse Anti-Human ErbB2/HER2 Monoclonal Antibody (Catalog # MAB11291) at 12ug/mL at 37 ° Celsius for 4 minutes. Before incubation with the primary antibody, tissue underwent an all-in-one dewaxing and antigen retrieval preprocessing using PreTreatment Module (PT Module) and Dewax and HIER Buffer H (pH 9). Tissue was stained using the Alexa Fluor™ 647 Goat anti-Mouse IgG Secondary Antibody at 1:200 at 37 ° Celsius for 2 minutes. (Yellow; Lunaphore Catalog # DR647MS) and counterstained with DAPI (blue; Lunaphore Catalog # DR100). Specific staining was localized to the cytoplasm. Protocol available in COMET™ Panel Builder.​

ErbB2/Her2 in Human Breast Cancer Tissue.

ErbB2/Her2 was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Mouse Anti-Human ErbB2/Her2 Herstatin Isoform Monoclonal Antibody (Catalog # MAB11291) at 8 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of cancer cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: ErbB2/Her2

Herstatin is a secreted 68 kDa glycoprotein encoded by an alternate transcript of the HER-2/neu (erbB-2) gene containing the N-terminal 304 amino acids (aa) of subdomain I and II, and 79 intron-encoded aa at the C-terminus. It is an endogenous inhibitor of the EGF receptor family that disrupts receptor interactions and inhibits growth of tumor cells that overexpress HER-2.
