TAT cell-penetrating peptide Penetrating peptides, scientifically known as cell-penetrating peptides (CPPs), represent a revolutionary class of molecules in the realm of molecular biology and therapeutics. These remarkable short peptides that facilitate cellular intake and uptake of molecules are fundamentally changing how we approach drug delivery and intracellular research. Comprised of short chains of amino acids, typically ranging from 4 to 40 amino acids in length, and often containing a net positive charge, CPPs possess the extraordinary ability to traverse cell membranes, which are otherwise formidable barriers to many compounds. This unique capability makes them invaluable tools for delivering a wide array of therapeutic agents and research molecules directly into the cellular interior.
