Scientific Data Images for Human/Rat Cortactin Antibody

Detection of Human and Rat Cortactin antibody by Western Blot.

Detection of Human and Rat Cortactin by Western Blot.

Western blot shows lysates of NTera-2 human testicular embryonic carcinoma cell line, MDA-MB-453 human breast cancer cell line, K562 human chronic myelogenous leukemia cell line, HeLa human cervical epithelial carcinoma cell line, and NRK rat normal kidney cell line. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human/Rat Cortactin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6096) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). 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.

Western Blot Shows Human Cortactin Antibody Specificity by Using Knockout Cell Line.

Western Blot Shows Human Cortactin Specificity by Using Knockout Cell Line.

Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and Cortactin knockout HeLa cell line (KO). PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Rat Cortactin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6096) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for Cortactin at approximately 80 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (Catalog # AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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.
