Stat5a, Phosphorylated (Tyr694) (Signal Transducer and Activator of Transcription 5A, Mammary Gland Factor, Mgf, Mpf)

Cat no: S7972-07U

Stat5a, Phosphorylated (Tyr694) (Signal Transducer and Activator of Transcription 5A, Mammary Gland Factor, Mgf, Mpf)

Membrane receptor signaling by various ligands induces activation of Jak kinases which then leads to tyrosine phosphorylation of the various Stat transcription factors. Stat1 and Stat2 are induced by IFN-a and form a heterodimer which is part of the ISGF3 transcription factor complex. Although early reports indicate Stat3 activation by EGF and IL-6, it has been shown that Stat3b appears to be activated by both while Stat3a is activated by EGF, but not by IL-6. Highest expression of Stat4 is seen in testis and myeloid cells. IL-12 has been identified as an activator of Stat4. Stat5 is activated by prolactin and by IL-3. Stat6 is involved in IL-4 activated signaling pathways.\n\nApplications:\nSuitable for use in Immunofluorescence and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nImmunofluorescence: 10-20ug/ml\nWestern Blot: 1-4ug/ml\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only.
