Lysis Using Dounce Homogenization
(Protocol summary only for purposes of this preview site)Dounce homogenization in combination with hypotonic buffers facilitates the lysis of adherent and suspension cells. Addition of hypotonic buffers results in the swelling of the cell's cytoplasm, allowing for the gentle rupture of cell membranes by mechanical force. Dounce homogenization releases cytoplasmic proteins that can be processed separately from the remaining intact nuclei, which can undergo high-salt extraction for detergent-free extraction of nuclear proteins. Application of this technique for cell lysis is particularly valuable when detergents must be avoided to preserve enzyme activity or proteinprotein interactions (Dignam et al. 1983a,b; Byers et al. 1988; Plopper and Ingber 1993; Grinnell and Ho 1995; Watarai et al. 2000; Dunn and Wobbe 2001; Simpson 2010; Bhaskaran et al. 2011). In the absence of detergents, high protein concentrations aid in protection of proteins from denaturation. This method works best with large cell numbers (5 107 cells) to achieve high protein concentrations of >5 mg/mL.
