Discontinuous buffer systems optimized for the agarose gel electrophoresis of subcellular particles

Abstract
Discontinuous buffer systems operative between pH 5.7 and 7.4, 0 °C, were generated, which are characterized by more rapidly displaced moving boundaries than applied previously. These allow one to resolve subcellular particles relatively rapidly and at relatively low agarose gel concentrations. A commercial mixture of DNA restriction fragments pre‐stained with ethidium bromide was found to be a suitable tracking dye for these boundaries.
