title: Theory for the capillary electrophoretic separation of DNA in polymer solutions.
abstract: We present a mathematical model based on the models of Hubert et al. [Macromolecules 29 (1996) 1006] and Sunada and Blanch [Electrophoresis, 19 (1998) 3128] to describe the electrophoretic mobility of DNA by a transient entanglement coupling mechanism. The proposed model takes into account the interactions between molecules in the capillary and the cross-section of collision between DNA and polymer molecules. The results show that the calculated values agree remarkably well with our electrophoretic mobility data.
