TAT peptide

The TAT peptide is a small chain of amino acids derived from the HIV virus's transactivator protein. Scientists utilize it as a delivery tool because it can efficiently cross cell membranes, allowing it to carry therapeutic molecules—like drugs or genetic material—inside cells. This property makes TAT peptides valuable in medicine and research, especially for targeting treatments directly to cells without invasive procedures. Their ability to penetrate cell barriers enhances the delivery of treatments for various diseases, including cancer and neurological disorders.
