Anti-Stat3 (p705) (Phospho) Antibody

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.

Store at 4°C if intended for use within one month, otherwise, store at -20°C to -80°C. The lyophilized antibody is stable for at least 18 months after the date of receipt when stored at -20°C to -80°C. After reconstitution, it can be aliquoted and stored frozen at -20°C to -80°C in a manual defrost freezer for at least 6 months without detectable loss of activity. Upon reconstitution, the antibody can also be stored for 1 month at 4°C. Please avoid multiple freeze-thaw cycles, as this will lower the activity of the antibody.

12 months from the date of shipment when stored properly.
