...ital. "A portion of the HIV protein called TAT can transport
biologically active compounds into cells. TAT is small, but it can move massive molecules. You could almost hook TAT up to a train, and TAT would drag it inside a cell. So we've taken advantage of this ability." In an article published online in Janu...
