Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 150 kDa (predicted molecular weight: 146 kDa).
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function
      Key enzyme in purine degradation. Catalyzes the oxidation of hypoxanthine to xanthine. Catalyzes the oxidation of xanthine to uric acid. Contributes to the generation of reactive oxygen species. Has also low oxidase activity towards aldehydes (in vitro).
    • Tissue specificity
      Detected in milk (at protein level).
    • Involvement in disease
      Defects in XDH are the cause of xanthinuria type 1 (XU1) [MIM:278300]. Xanthinuria is characterized by excretion of very large amounts of xanthine in the urine and a tendency to form xanthine stones. Uric acid is strikingly diminished in serum and urine. XU1 is due to isolated xanthine dehydrogenase. XU1 patients can metabolize allopurinol.
    • Sequence similarities
      Belongs to the xanthine dehydrogenase family.
      Contains 1 2Fe-2S ferredoxin-type domain.
      Contains 1 FAD-binding PCMH-type domain.
    • Post-translational
      Subject to partial proteolysis; this alters the enzyme from the dehydrogenase form (D) to the oxidase form (O).
      Contains sulfhydryl groups that are easily oxidized (in vitro); this alters the enzyme from the dehydrogenase form (D) to the oxidase form (O).
    • Cellular localization
      Cytoplasm. Peroxisome. Secreted.
