Grinding of leaves for extraction of nucleic acids

One of the most traditional and common methods for harvesting nucleic acids from plants involves grinding leaves in liquid nitrogen with a mortar and pestle. Either the mortar and pestle can be pre-chilled and the grinding performed dry on frozen leaves, or the leaves can be submersed in liquid nitrogen for the grinding. Cryogenic grinding is a very effective technique for taking hard substances, like plant and animal tissues, …
