RNA extraction is the purification of RNA from biological samples. This procedure is complicated by the ubiquitous presence of ribonuclease enzymes in cells and tissues, which can rapidly degrade RNA.[1] Several methods are used in molecular biology to isolate RNA from samples, the most common of these is Guanidinium thiocyanate-phenol-chloroform extraction.[2][3]

RNA extraction in liquid nitrogen, commonly using a mortar and pestle, or specialised motorized grinding device [cell lysis device] is also useful in preventing ribonuclease activity.
