Abstract

An ensemble of components and methods are disclosed for utilizing two-dimensional electrophoresis in polyacrylamide or related polymer gels using common, existing and familiar electrophoresis formats and equipment. The disclosed invention makes two-dimensional electrophoresis convenient and easy to use for individuals already using vertical “mini-gel” type systems. The invention discloses the combination of pre-cast disposable gels for both first and second separation dimensions using novel support devices and cassettes that simplify the difficult multiple sample handling and processing steps inherent in ordinary two-dimensional electrophoresis methods. Devices and methods are disclosed in said invention that provide exceptional gel to gel reproducibility.
