Data Examples
Detection of Human Cortactin by Western Blot. Western blot shows lysates of A549 human lung carcinoma cell line and K562 human chronic myelogenous leukemia cell line. PVDF membrane was probed with 0.1 µg/mL of Mouse Anti-Human Cortactin Monoclonal Antibody (Catalog # MAB6096) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). Specific bands were detected for Cortactin at approximately 80-85 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Immunohistochemistry
Cortactin in Human Prostate. Cortactin was detected in immersion fixed paraffin-embedded sections of human prostate using Mouse Anti-Human Cortactin Monoclonal Antibody (Catalog # MAB6096) at 15 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 # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to the plasma membranes of glandular epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: Cortactin

Cortactin (also EMS1 and Amplaxin) is an 80‑85 kDa multidomain scaffold-associated protein. It is an actin-binding cytoplasmic protein found at intercellular junctions and near lamellipodia. It is also found in tumor invadopodia, a somewhat analogous structure to lamellipodia. Here, Cortactin appears to coordinate actin assembly with MMP secretion, thus facilitating tumor invasiveness. Human Cortactin is 550 amino acids (aa) in length and contains six-plus Cortactin regions (aa 80‑324) that regulate actin polymerization, and one SH3 domain (aa 496‑548) that binds to N-WASP. Cortactin is highly phosphorylated on Tyr and Ser/Thr, and undergoes acetylation.
