Copolymers prepared by the free radical copolymerization of acrylamide and vinyl malachite green were immobilized in an agarose gel matrix to produce a novel affinity gel for double-stranded DNAs. Relative electrophoretic mobilities of calf thymus DNA and poly(dA-dT)2 strongly depended on the amount of vinyl malachite green to show the strong interaction between DNAs and the copolymers. But any affinity interaction was not observed between poly(dG-dC)2 and the copolymers.
