Data Examples

Immunohistochemistry ErbB2/Her2 in Human Breast. View Larger

ErbB2/Her2 in Human Breast. ErbB2/Her2 was detected in immersion fixed paraffin-embedded sections of human breast using Mouse Anti-Human ErbB2/Her2 Herstatin Isoform Monoclonal Antibody (Catalog # MAB11291) at 25 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). 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.
