Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
STAT proteins (Signal Transduction and Activators of Transcription) are latent cytoplasmic transcription factors that have the dual function of signal transduction and activation of transcription. STATs are activated by tyrosine phosphorylation in response to different ligands, after which they translocate to the cell nucleus. The N-terminal region is highly homologous among the STAT proteins and surrounds a completely conserved arginine residue. STATs are a part of the JAK-STAT signaling pathway a major pathway of the immune system. All cytokines transduce critical signals through this pathway. STAT 1, is activated by a number of different ligands, including IFNalpha, IFNgamma, EGF, PDGF and IL-6. Phosphorylation of tyrosine 701 is required for STAT 1 dissociation from IFNGR1, homodimerization, and nuclear translocation. Tyrosine 701 phosphorylation impairment results in loss of STAT 1 functions.
Catalog #S7969-08
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 1:5001:200 dilution detects phosphorylated STAT1 in RIPA lysates from CNTF-treated SK-N-MC cells. 20ug of non-treated or CNTF-treated SK-N-MC cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with S7969-08. Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.
ControlMouse 3T3-L1 adipocytes stimulated with leukemia inhibitory factor (LIF)
