    Traditional Methods of Cell Lysis Thermo Fisher

    Manual grinding is the most common method used to disrupt plant cells. Tissue is frozen in liquid nitrogen and then crushed using a mortar and pestle. Because of the tensile strength of the cellulose and other polysaccharides comprising the cell wall this method is the fastest and most efficient way to access plant proteins and DNA.
