Overview

  • Product nameAnti-STAT5a (phospho Y694) antibody
    See all STAT5a primary antibodies
  • Description
    Rabbit polyclonal to STAT5a (phospho Y694)
  • Specificityab30648 detects endogenous levels of STAT5A only when phosphorylated at Tyrosine 694. Antibody ab31377 is raised against the same peptide sequence but non-phosphorylated at tyrosine 694.
  • Tested applicationsSuitable for: WB, ELISA, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic phosphopeptide derived from human STAT5a around the phosphorylation site of Tyrosine 694.

  • Positive control
    • Breast carcinoma tissue; HeLa cells treated with EGF.

Applications

Our Abpromise guarantee covers the use of ab30648 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
WB 1/500 - 1/1000. Detects a band of approximately 90 kDa (predicted molecular weight: 91 kDa).
ELISA 1/20000.
IHC-P Use at an assay dependent concentration.

Target

  • FunctionCarries out a dual function: signal transduction and activation of transcription. Binds to the GAS element and activates PRL-induced transcription.
  • Sequence similaritiesBelongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • Post-translational
    modifications
    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 localizationCytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.
