Primary antibody notesab52211 detects endogenous levels of STAT5B but only when phosphorylated at serine 731 (human) or serine 730 (mouse and rat).
Our Abpromise guarantee covers the use of ab52211 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 1 - 5 µg/ml.|
|WB||1/500 - 1/1000. Detects a band of approximately 90 kDa (predicted molecular weight: 90 kDa).|
|IHC-P||Use at an assay dependent concentration.|
FunctionCarries out a dual function: signal transduction and activation of transcription. Mediates cellular responses to the cytokine KITLG/SCF and other growth factors. Binds to the GAS element and activates PRL-induced transcription.
Involvement in diseaseGrowth hormone insensitivity with immunodeficiency
Sequence similaritiesBelongs to the transcription factor STAT family.
Contains 1 SH2 domain.
modificationsTyrosine phosphorylated in response to signaling via activated KIT, resulting in translocation to the nucleus. Tyrosine phosphorylated in response to signaling via activated FLT3; wild-type FLT3 results in much weaker phosphorylation than constitutively activated mutant FLT3. Alternatively, can be phosphorylated by JAK2. Phosphorylation at Tyr-699 by PTK6 or HCK leads to an increase of its transcriptional activity. Dephosphorylation on tyrosine residues by PTPN2 negatively regulates prolactin signaling pathway.
Cellular localizationCytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.

Paraffin-embedded human breast carcinoma tissue stained for STAT5b (phospho S731), using ab52211 (1/100). The right hand panel represents a negative control where ab52211 was pre-incubated with the immunising (blocking) peptide.
ICC/IF image of ab52211 stained HeLa cells. The cells were 4% PFA fixed (10 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 (ab52211, 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.
