The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Dot blot 1/1000.
WB 1/1000 - 1/10000. Detects a band of approximately 90 kDa (predicted molecular weight: 90 kDa).
  • Application notes
    Is unsuitable for FuncS,ICC or IHC-P.
  • Target

    • Function
      Carries out a dual function: signal transduction and activation of transcription. Binds to the GAS element and activates PRL-induced transcription.
    • Sequence similarities
      Belongs to the transcription factor STAT family.
      Contains 1 SH2 domain.
    • Post-translational
      Tyrosine phosphorylated in response to IL-2, IL-3, IL-7, IL-15, GM-CSF, growth hormone, prolactin, erythropoietin and thrombopoietin. Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity.
    • Cellular localization
      Cytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.
