Scientific Data

Western Blot Detection of Mouse Patched 1/PTCH antibody by Western Blot. View Larger

Detection of Mouse Patched 1/PTCH by Western Blot. Western blot shows lysates of MEF mouse embryonic feeder cells, Neuro-2A mouse neuroblastoma cell line, and mouse brain tissue. PVDF Membrane was probed with 1 µg/mL of Rat Anti-Human/Mouse Patched 1/PTCH (First Extracellular Loop) Monoclonal Antibody (Catalog # MAB41051) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Patched 1/PTCH at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Patched in Mouse Spinal Cord. Patched was detected in immersion fixed frozen sections of mouse spinal cord using 10 µg/mL Rat Anti-Human/Mouse Patched 1/PTCH (First Extracellular Loop) Monoclonal Antibody (Catalog # MAB41051) overnight at 4 °C. Tissue was stained (red) and counterstained with DAPI (blue). View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Patched 1/PTCH in Human Esophageal Squamous Cell Carcinoma. Patched 1/PTCH was detected in immersion fixed paraffin-embedded sections of human esophogeal squamous cell carcinoma tissue using Rat Anti-Human/Mouse Patched 1/PTCH (First Extracellular Loop) Monoclonal Antibody (Catalog # MAB41051) at 15 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 staining was localized to plasma membranes.

Background: Patched 1/PTCH

Patched homolog 1 (PTCH, also called PTC, PTC1 or PTCH1) is a 170‑175 kDa member of the Patched family of proteins. It is found on multiple cells types and forms a constitutive, inactivating complex with Smoothened. Upon SHH binding to PTC1, Smoothened is released and initiates downstream signaling. Mouse PTCH is a 12 transmembrane, 1434 aa glycoprotein that contains two terminal cytoplasmic domains. Only one mRNA species for PTCH has been reported in mice. However, it would appear likely that two or more splice forms exist, with variation occurring over the first 150 aa of the N-terminus. Over aa 108‑422, mouse PTCH shares 97% and 99% aa sequence identity with human and rat PTCH, respectively.
