The method is based on measurement of two tryptophan-specific signals in … WebDetergent-based cell lysis. Both denaturing and non-denaturing cell lysis reagents may be used for protein extraction procedures. Denaturing detergents such as SDS bind to both membrane (hydrophobic) and non-membrane (water-soluble, hydrophilic) proteins at concentrations below the CMC (i.e., as monomers). The reaction is equilibrium driven ...
