TAT Peptide TFA（Cat No.:I044769）is a cell-penetrating peptide derived from the HIV-1 TAT protein (typically YGRKKRRQRRR). It efficiently translocates across cellular membranes, making it a powerful tool for intracellular delivery of various biomolecules, including proteins, nucleic acids, and nanoparticles. Its rich arginine and lysine content facilitates interaction with negatively charged cell membranes, enabling rapid uptake. Supplied as a trifluoroacetate (TFA) salt for stability and solubility, TAT peptide is widely used in drug delivery, molecular biology, and therapeutic research to enhance cellular uptake of otherwise impermeable compounds.
