Copolymer solutions as separation media for DNA capillary electrophoresis

A review on copolymers used as DNA separation media in capillary electrophoresis is presented. Copolymers can combine the desirable properties of different monomers, yielding many attractive features, such as high sieving ability, low viscosity, self-assembly behavior and dynamic coating ability. Copolymers with different molecular architecture, including block copolymers, random copolymers, and graft copolymers, have been developed and tested as DNA separation media with unique and tailored properties that cannot be achieved easily by using only homopolymers.
