Grinding of leaves for extraction of nucleic acids

The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low. Preventing sample warming can be done be adding additional liquid nitrogen to the mortar while pulverizing the sample.
