Family of modified-tripeptide protease inhibitors. Commonest is N-acetyl-Leu-Leu-argininal.
It is often used during in vitro experiments when a specific enzymatic reaction is being studied. When cells are lysed for these studies, proteases, many of which are contained within lysosomes, are released. These proteases, if freely present in the lysate, would destroy any products from the reaction being studied, and make the experiment uninte...Found on http://en.wikipedia.org/wiki/Leupeptin
