Lysis (/ËlaÉªsáµ»s/ LY-sÉs; Greek Î»ÏÏÎ¹Ï lÃ½sis, a loosing from Î»ÏÎµÎ¹Î½ lÃ½ein, to unbind) refers to the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, lytic /ËlÉªtáµ»k/ LIT-Ék) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate. In molecular biology, biochemistry, and cell biology laboratories, cell cultures may be subjected to lysis in the process of purifying their components, as in protein purification, DNA extraction, RNA extraction, or in purifying organelles.
