Abstract
Compositions useful as a separation medium in capillary electrophoresis procedure and methods for their use in capillary electrophoresis are described. The compositions include dry linear polyacrylamide which is capable of hydrating to form an aqueous polymeric system capable of filling an electrophoresis capillary column. Also disclosed are methods for using dry polyacrylamide in capillary electrophoresis. The methods include providing a dry polyacrylamide composition, reconstituting the dry polymer to provide a solution of reconstituted polymer, and causing the reconstituted polymer to fill a capillary electrophoresis column.
