STAT 5, phosphorylated (Tyr694) Kit, BioAssay(TM) (Signal Transducer and Activator of Transcription 5)

The Phosphorylated Stat5 (Tyr694) Antibody Kit provides reagents and protocols for the rapid analysis of the phosphorylation status of Stat5 at tyrosine 694. Stat5 is activated in response to a wide variety of ligands including IL-2, GM-CSF, growth hormone and prolactin. Phosphorylation on residue Tyr694 is obligatory for Stat5 activation. Stat5 has been found to be constitutively active in some leukemic cell types. Phosphorylated St at5 is found in some endothelial cells treated with IL-3, which suggests its involvement in angiogenesis and cell motility. Stat5a and-b are independently regulated and activated in various cell types. For instance, both isoforms are activated in response to IFN-a in B cells, but only Stat5a is phosphorylated in response to IFN-a in HeLa cells.
