BBC microcomputer controlled field inversion gel electrophoresis

Abstract
Agarose gel electrophoresis to separate DNA molecules is a widely used technique in molecular biology but there is an upper limit to the sizes that can be resolved. Pulsed field techniques have extended this limit but require expensive equipment. Here we describe a home-made control unit to interface conventional electrophoresis equipment to a BBC microcomputer for the purposes of field inversion gel electrophoresis.
