Abstract
A process of separating plasmids and cosmids from bacterial cells in which they are contained, comprising adding cultured bacterial cells separated from a culture medium to an inclusion gel-forming substance; lysing the bacterial cells; solubilizing the thus lysed bacterial cells; solidifying the inclusion gel-forming substance to form a gel either before or after the step of solubilizing; and applying an electric field to the thus formed gel sufficient to cause electrophoretic migration of the plasmids and cosmids and isolation of the plasmids and cosmids. Also disclosed is a device for carrying out the process.
