  • Publication number: 20030224436
    Abstract: Integrated microfluidic devices comprising at least an enrichment channel (10) and a main electrophoretic flowpath (12) are provided. In the subject integrated devices, the enrichment channel and the main electrophoretic flowpath are positioned so that waste fluid flows away from said main electrophoretic flowpath through a discharge outlet (6). The subject devices find use in a variety of electrophoretic applications, including clinical assays, high throughput screening for genomics and pharmaceutical applications, point-or-care in vitro diagnostics, molecular genetic analysis and nucleic acid diagnostics, cell separations, and bioresearch generally.

  • Patent number: 5885432
    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.

  • Patent number: 5883211
    Abstract: Thermoreversible hydrogels comprising non-ionic, uncrosslinked copolymers, and methods of their use in electrophoresis, are provided. The subject copolymers comprise polyacrylamide backbones, where a portion of the acrylamide monomeric units comprise hydrogen bonding groups as N-substituents. Combination of the subject copolymers with an aqueous phase provides thermoreversible hydrogels which find use as separation media in electrophoretic applications.
