Descripción

General description

Supplied as a trifluoroacetate salt.

A cell-permeable analog of the Stat3-SH2 domain-binding phospho-peptide (Cat. No. 573095) that contains a C-terminal membrane translocating sequence (MTS) and acts as a highly selective, potent blocker of Stat3 activation. Also suppresses constitutive Stat3-dependent Src transformation with no effect on Stat3-independent Ras transformation.
