APC in Human Colon Cancer Tissue. APC was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using 15 µg/mL Goat Anti-Human APC C-Terminus Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3695) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

APC is a ubiquitous, tumor-suppressor protein that is mutated in most colon cancers, generally resulting in a gene product that is truncated in the carboxy terminal region. APC contains several binding domains. The region used as an immunogen overlaps the EB1, DLG (PDZ sequence), and PSD-93 domains. These domains bind microtubules, mitotic spindles, and F-actin and are involved in cell cycle, division, and migration. The immunogen does not include the beta -catenin-binding region, which antagonizes Wnt signaling. The human APC amino acid sequence used as immunogen is 83% and 86% identical to mouse and rat APC, respectively.
