APPARATUS FOR PREPARATIVE GEL ELECTROPHORESIS, IN PARTICULAR FOR SEPARATING MIXTURES ON A GRADIENT GEL POLYACRYL AMIDE COLUMN

摘要

A preparative gel electrophoresis apparatus comprises a first outer coolable cylinder, a second inner coolable cylinder within the outer cylinder, a compact column of separating material placed between the first and second cylinders and electrodes arranged above and below the separating column for forming an electrical field over the volume of the separating column, axially translatable adapters above and below the support, surrounding the electrodes, containing duct systems and completely surrounding the inner coolable cylinder. A method of forming the gel column by injecting gel while separating the adapters is also disclosed.
