      This product has been discontinued.



      A Stat3-SH2 domain binding phosphopeptide that acts as a selective inhibitor of Stat3 (signal transducers and activators of transcription 3) signaling with a DB50 of 235 µM (concentration of peptide at which DNA-binding activity is inhibited by 50%). Significantly lowers the DNA-binding activity of Stat3 by forming an inactive Stat3:peptide complex and reduces the levels of active Stat3:Stat3 dimers that can bind DNA. Displays greater affinity for Stat3, and to a lesser extent Stat1, over Stat5.

      Supplied as a trifluoroacetate salt.
