Technical Data
STAT3 Inhibitor V, Stattic (Signal Transducer and Activator of Transcription 3, Acute-phase Response Factor, APRF)
Biochemicals Storage: 4CShipping: RT
STAT3 protein is a transcription factor expressed in most cell types and is activated by multiple cytokines and growth factors including: IFN-a, IL-10, IL-6, IL-11, IL-12, IL-2, EGF etc. STAT3 binds to DNA as either a homodimer or as a heterodimer with STAT1. STAT3 interacts with the APRE (acute phase response element) & SIE (c-sis inducible element).

STAT3 Inhibitor V, Stattic is a cell-permeable vinyl-sulfone compound that acts as an inhibitor of STAT3 cellular function by targeting the STAT3-SH2 domain and preventing its association with upstream kinases. The effect of Stattic towards STAT family members is temperature-dependent and appears to be highly STAT3-selective at 37C. Shown to inhibit cellular phosphorylation of STAT3 at Tyr705 with little effect towards STAT1 phosphorylation at Tyr701 (in HepG2 cells) or the phosphorylation of JAK1, JAK2, and c-Src (in MDA-MB-231 and MDA-MB-235S cells).


Suitable for use in ELISA, Inhibition Assays and Western Blot. Other applications not tested.
