Use of capillary electrophoresis as a method development tool for classical gel electrophoresis

Abstract

Capillary electrophoresis (CE) was used to optimize the buffer pH, ionic strength and sulfated cyclodextrin concentrations for enantiomeric separation of piperoxan. These enantioseparation conditions were then applied to a classical gel electrophoresis system. Binding constants of the sulfated β-cyclodextrin–piperoxan couple were approximated using CE and the effects of organic solvents on the system were also investigated.
