Our Abpromise guarantee covers the use of ab30649 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
ICC/IF Use a concentration of 1 µg/ml.
WB 1/500 - 1/1000. Detects a band of approximately 91 kDa (predicted molecular weight: 91 kDa).
ELISA 1/10000.
IHC-P Use at an assay dependent concentration.


  • 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
    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.

  • ICC/IF image of ab30649 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab30649, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
