Anti-Stat3 (p705) (Phospho) Antibody, Biotinylated

STAT3 is also called as signal transducer and activator of transcription 3 (acute phase response factor); APRF; DNA-binding protein APRF (acute-phase response factor). The Stat proteins function as both cytoplasmic signal transducers and activators of transcription. Stat3 is a 92kDa protein that is activated as a DNA binding protein through tyrosine phosphorylation in response to treatment of cells with EGF and IL-6 but not with IFN-?. Stat3 is widely expressed and can bind to DNA in the absence of Stat1a or Stat2. Stat3 can bind to the sis-inducible element (SIE) site from the c-fos promoter. The site is similar to the GAS element that is present in IFN-? induced genes. It appears that Stat3 binds to DNA as a homodimer, but it is also capable of binding as a heterodimer with Stat1. With the isolation of Stat3 and the discovery of Stat4, it appears that the Stat family may contain many members, each with a characteristic tissue distribution and specific activating ligands.

The antibody is stable for at least 1 year from the date of receipt when stored at -20°C to -70°C. Reconstituted antibody can also be aliquotted and stored at 4°C for 1 month or at -20°C to -70°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.

This antibody binds to its immunogen, and did not show any cross reactivity with unrelated antigens in ELISA. Cross reactivity with mouse and rat STAT3 has not yet been tested.
