Abstract
Electrophoretic media are provided comprising at least un-crosslinked polymers which have a temperature reversible transition from low viscosity to high viscosity, so as to be pourable at one temperature, while providing sieving properties at another temperature. Optionally included with the un-crosslinked polymers having a reversible temperature responsive viscosity change are gelling agents and polymers which do not have the reversible temperature responsive viscosity change. The subject compositions have excellent clarity, provide excellent separation and resolution, handling properties, and mechanical strength. The compositions are compatible with transfer of separated components from the gel to an accepting membrane.
