ABSTRACT:
An electrophoretic matrix comprised of at least one water-insolubilized, temperature-responsive polymeric compound having an LCST is disclosed. The electrophoretic matrix can change its hydrophilic/hydrophobic property by changing temperature. A method of using the electrophoretic matrix involves charging a sample onto the matrix and carrying out electrophoresis at a temperature above or below the LCST of the polymeric compound.
