title: Effect of temperature on the separation of long DNA fragments in polymer solution.
abstract: Electrophoresis of long DNA fragments in polymer solutions is still attractive when performed in short capillaries. Then the separations can be accomplished in minutes rather than hours as is usual in various slab electrophoresis techniques. In this paper we focused on the behavior of large DNA fragments in pulsed field capillary electrophoresis under various temperature conditions. The mobility dependence of fragments of lambda-DNA single-cut mixture on various frequencies at three different temperatures showed that the antiresonance mobility minima are shifted to higher frequencies at higher temperatures. This interesting result is explained in terms of the geometration model of DNA motion.
