  • Publication number: 20030180449
    Abstract: Methods for controlled application of a composition gradient to a surface, via controlled targeting of droplets of different solutions to a surface region, are disclosed. The methods are especially useful for delivering a gradient of first and second solutions to a microchannel within a microchannel device, by targeting droplets of the different solutions to a surface region within or adjacent an opening of the microchannel.

  • Patent number: 6214191
    Abstract: Disclosed are an apparatus, system, and method for two dimensional electrophoresis of analytes of interest, particularly polypeptides. The apparatus includes a sample separation cavity comprising (1) an electrophoresis region located along an upper portion of the cavity for performing charge and/or size-based electrophoresis in a first dimension along the upper portion, and (2) below the electrophoresis region, a second electrophoresis region for performing electrophoresis in a second dimension in a direction substantially perpendicular to the first dimension. In one preferred embodiment, the second electrophoresis region contains an isoelectric focusing region containing a continuous pKa gradient immobilized on at least one of the major opposing surfaces of the cavity.

  • Patent number: 5264101
    Abstract: A capillary tube with a charged inner surface for use in capillary electrophoresis and methods. The tube is filled with an electrolyte solution containing 0.05-30% weight/weight of a hydrophilic polymer which is characterized by (A) a molecular weight of 20-5,000 kilodaltons, and (B) a charge between 0.01 and 1.0% as measured by the molar percent of charged monomer subunits to the total polymer subunits, where said charged monomer subunits have the charge opposite to the wall charge at a selected electrophoresis pH.

  • Patent number: 5181999
    Abstract: A method for achieving desired electroosmotic flow characteristics in a capillary tube having charged surface groups. An electrolyte solution containing a compound effective to stably alter the charge of the tube walls is drawn into and through the tube during while the electroosmotic flow rate in the tube is being monitored, until a desired electroosmotic flow rate is achieved. The method can be used to optimize electrophoretic separation of charged protein or nucleic acid species in a capillary tube, and to produce capillary tubes with desired charge density properties.
