    See all STAT3 primary antibodies
  • Description
    Rabbit polyclonal to STAT3 (phospho S727)
  • SpecificityThis antibody recognizes STAT3 with a phosphorylated site at Serine 727. It does not cross react with non phosphospecific peptide.
  • Tested applicationsWB, ELISA, IP, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Chicken, Cow, Dog, Human
  • Immunogen

    A synthetic peptide surrounding to the epitope -PMSPR- with phosphorylation at Ser727 of STAT3.

  • Positive control
    • EGF stimulated A431 whole cell lysate
  • General notes

    STAT3 is constitutively activated in a number of human tumors. STAT3 activated transcription seems to be regulated by serine phosphorylation at Serine 727.



Our Abpromise guarantee covers the use of ab97686 in the following tested applications.

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

Application Abreviews Notes

IHC-P 1/50.


  • FunctionTranscription factor that binds to the interleukin-6 (IL-6)-responsive elements identified in the promoters of various acute-phase protein genes. Activated by IL31 through IL31RA.
  • Tissue specificityHeart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
  • Involvement in diseaseDefects in STAT3 are the cause of hyperimmunoglobulin E recurrent infection syndrome autosomal dominant (AD-HIES) [MIM:147060]; also known as hyper-IgE syndrome or Job syndrome. AD-HIES is a rare disorder of immunity and connective tissue characterized by immunodeficiency, chronic eczema, recurrent Staphylococcal infections, increased serum IgE, eosinophilia, distinctive coarse facial appearance, abnormal dentition, hyperextensibility of the joints, and bone fractures.
  • Sequence similaritiesBelongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • Post-translational
    Tyrosine phosphorylated upon stimulation with EGF (By similarity). Tyrosine phosphorylated in response to IL-6, IL-11, CNTF, LIF, CSF-1, EGF, PDGF, IFN-alpha and OSM. Phosphorylated on serine upon DNA damage, probably by ATM or ATR. Serine phosphorylation is important for the formation of stable DNA-binding STAT3 homodimers and maximal transcriptional activity. ARL2BP may participate in keeping the phosphorylated state of STAT3 within the nucleus.
  • Cellular localizationCytoplasm. Nucleus. Shuttles between the nucleus and the cytoplasm. Constitutive nuclear presence is independent of tyrosine phosphorylation. Predominantly present in the cytoplasm without stimuli. Upon leukemia inhibitory factor (LIF) stimulation, accumulates in the nucleus. The complex composed of BART and ARL2 plays an important role in the nuclear translocation and retention of STAT3.
