InCELLect St-Ht31P Control Peptide is a stearated form of the peptide Ht-31P. This peptide has been used as a negative control peptide for the study of InCELLect AKAP St-Ht31 Inhibitor Peptide. The presence of the hydrophobic stearated moiety enhances the cellular uptake of the peptide, allowing it to be used to study PKA signaling in intact cells in culture.
