Application Abreviews Notes
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/2000 - 1/10000. Detects a band of approximately 68 kDa (predicted molecular weight: 68 kDa).
IP Use at 2-5 µg/mg of lysate.


  • Function
    Component of the PeBoW complex, which is required for maturation of 28S and 5.8S ribosomal RNAs and formation of the 60S ribosome.
  • Tissue specificity
    Significant levels are detected in a variety of cancer cell lines, including glioblastoma, breast carcinoma, colon carcinoma and cervical carcinoma cells. Levels are abnormally elevated in malignant tumors of astrocytic origin.
  • Sequence similarities
    Belongs to the pescadillo family.
    Contains 1 BRCT domain.
  • Post-translational
  • Cellular localization
    Nucleus > nucleolus. Nucleus > nucleoplasm. Chromosome. Appears to localize to the periphery of metaphase chromosomes during mitosis and to the prenucleolar bodies that form in mitotic cells prior to the actual nucleoli.

  • All lanes : Anti-Pescadillo antibody (ab72539) at 0.04 µg/ml

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg
    Lane 4 : 293T whole cell lysate at 50 µg

    Predicted band size : 68 kDa
    Observed band size : 68 kDa
    Additional bands at : 31 kDa. We are unsure as to the identity of these extra bands.
  • Detection of Human Pescadillo by Immunoprecipitation from Whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded), using ab72539 at 3 µg/mg lysate for IP and at 1 µg/ml for subsequent Western blot detection.
