The concentration of the detergent is also a variable that affects particle quality. Most detergent-stabilized membrane protein structures are solved using detergent concentrations at or below the critical micelle concentration (CMC), and this range may be a good starting point for single particle EM projects.

Detergents and their role in successful SDS-PAGE ...

Furthermore, detergents interfere with any non-covalent interactions between individual amino acids in the protein thereby reducing the globular protein to a linear chain of amino acids. By doing this all of the proteins in the sample will have essentially a uniform charge and all migrate at the same rate with respect to their charge, thus ...
