Patent ID: 6939453

Claim:
An electrophoresis separation process for separating a sample into its components, said process comprising the steps of: providing an electrophoresis gel comprising a polymeric gel material having a dimension sufficient to separate molecules and having a first end and a second end, a sample in contact with said gel, a first electrically conductive organic liquid at said first end, a second electrically conductive organic liquid at said second end, and applying an electric potential between said first end and said second end of said gel to cause said components in said sample to migrate through said gel from said first end toward said second end and electrophoretically separating components of said sample, wherein the electrophoresis gel is a polyurethane or polyurea-urethane based gel and said first organic liquid is compatible with said polyurethane or polyurea-urethane, and wherein said first and second organic liquids include at least one organic solvent selected from the group consisting of alcohols, ketones, nitriles, alkanes, alkenes, cycloalkanes, cycloalkenes, aromatic compounds, heterocyclic compounds, and mixtures thereof.
