Our Abpromise guarantee covers the use of ab219607 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 Use at an assay dependent concentration. Detects a band of approximately 90 kDa (predicted molecular weight: 90 kDa).
IHC-P Use at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
  • Application notes
    Is unsuitable for ICC/IF or IP.
  • 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.

    • Serially diluted ab32364 was bound to immobilised phospho peptide (P) - or control peptides ((C), 1 microgram x mL-1). The antibody was detected by HRP-labelled goat anti-rabbit IgG (ab97080; diluted 1: 50,000) and signal was developed with TMB substrate

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32364).

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human infiltrating duct carcinoma of breast tissue labelling STAT5 (phospho Y694) with purified ab32364 at 1/50. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a HRP-conjugated goat anti-rabbit IgG (H+L) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32364).

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma using unpurified ab32364 at a 1/50 dilution.

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32364).
