Detection of Human, Mouse, and Rat Park7/DJ‑1 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, MEF mouse embryonic feeder cells, and C6 rat glioma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse/Rat Park7/DJ‑1 Monoclonal Antibody (Catalog # MAB39951) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Park7/DJ‑1 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Park7/DJ‑1 in HeLa Human Cell Line. Park7/DJ‑1 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human/Mouse/Rat Park7/DJ‑1 Monoclonal Antibody (Catalog # MAB39951) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Park7, also known as DJ-1, is a cytoplasmic protein that belongs to the
ThiJ/Pfp1/DJ-1 superfamily of highly conserved proteins that function
as protein chaperones, catalases, proteases and kinases. Park7 is
widely expressed in the brain as well as in peripheral tissues. It
exists as a homodimer that can be localized in the cytoplasm, nucleus
and mitochondria. Park7 is a redox-sensitive protein that has been
ascribed various functions including that as a redox sensor and
antioxidant protein. Mutations in Park7 are associated with a small
percentage of hereditary early onset Parkinson’s disease. Human and
mouse Park7 share 92% amino acid sequence identity.
