Abstract: Macromolecules are electroeluted from a matrix by placing the matrix containing the macromolecules of interest in a container, forcing the matrix toward the tip of the container, e.g., by centrifugation, providing an opening at the tip of the container large enough to pass the component, but not the matrix, inserting that container inside another container, placing an electrode in each container together with enough electrophoresis buffer to immerse each electrode, and applying a voltage across the electrodes for a time and under conditions sufficient to cause the macromolecules but not the matrix to migrate from the first container into the second. A kit for performing the electroelution is also described.
