Abstract: A protein transfer system includes at least one base configured to receive one or more consumable protein transfer stacks and at least one lid configured to cover the base. The lid(s) comprise(s) one or more electrodes for supplying current to the one or more consumable protein transfer stacks. The protein transfer system further includes at least one voltage source configured to supply the current to the one or more consumable protein transfer stacks, one or more processors, and one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the protein transfer system to control operation of the one or more voltage sources.

Abstract: Cassette electrophoresis systems that allow viewing of molecules during the electrophoresis run are disclosed. Cassette electrophoresis bases that reversibly engage light sources, such as light source bases are disclosed. Also disclosed are visible light transillumination systems for viewing a pattern of fluorescence emitted by fluorophores comprising a cassette housing fluorophore-containing material and a base unit to support the cassette. In some aspects the base unit that includes a power supply also houses a light source having output in the visible wavelength region and a filter placed between the light source and the fluorophores. The system is constructed and arranged such that patterns of fluorescence emitted by the fluorophores are viewable. Also described are charging devices for providing charge to gel electrophoresis systems, portable gel electrophoresis systems and methods of use thereof.
