Abstract
Porous plastic electrophoresis sponges having pore sizes range from 10.sup.-9 to 10.sup.-3 meters. The sponges are made from polyethylene, polypropylene, polytetrafluoroethylene, polyvinylidine difluoride, polynitrile or polystyrene. The porous plastic sponges are commercially available and are supplied in a prefabricated form which eliminates the preparative and pouring steps required for conventional gel electrophoresis support media. The porous sponges are available in a range of pore sizes and densities for use in a variety of electrophoresis systems to separate a variety of different materials including proteins, peptides and DNA. The porous electrophoresis sponges are relatively inert and may be used with organic solvents.
