Theory of gel electrophoresis of DNA: Orientational effects

Abstract
Some aspects of the reptation model of gel electrophoresis of DNA, with emphasis on the orientational effects, are considered. A master equation for the reptational dynamics with the end boundary conditions is proposed. Based on this equation, the orientation and dynamics of the persistent‐chain are investigated. In particular, the role of trap conformations for this chain, which essentially reduce the chain mobility, was analyzed. A transient orientation of the chain during pulsed field gel electrophoresis is also discussed.
