Cryogenic grinding - Wikipedia

2019-4-14 · Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.

Influence of Cryogenic Grinding on Release of Protein

Protein and DNA released by mechanical disruption are amenable to degradation due to high shear and temperature rise in conventional processes. In the present work cryogenic grinding has been employed for the first time to disrupt yeast cell by embrittlement at -196 degC, which results in less denaturation of intracellular protein and DNA.
