Detection of Human and Rat PTK7/CCK4 by Western Blot.
Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and Rat‑2 rat embryonic fibroblast cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human/Rat PTK7/CCK4 Monoclonal Antibody (Catalog # MAB4499) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PTK7/CCK4 at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
PTK7/CCK4 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Mouse Anti-Human/Rat PTK7/CCK4 Monoclonal Antibody (Catalog # MAB4499) 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). Specific labeling was localized to the cytoplasm of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for PTK7/CCK4 at approximately 168 kDa (as indicated) using 20 µg/mL of Mouse Anti-Human/Rat PTK7/CCK4 Monoclonal Antibody (Catalog # MAB4499). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

Protein tyrosine kinase 7 (PTK7), also known as colon carcinoma kinase 4 (CCK4), is a receptor tyrosine kinase (RTK) involved in colon carcinoma development and/or proliferation. Similar to the RTK HER3, PTK7 contains a catalytically inactive tyrosine kinase domain, suggesting a potential tumor-characteristic role as a signal amplifier or modulator for an as yet unidentified kinase-competent partner. PTK7 may also play a role during gastrulation in the rodent embryo.
