    摘要: Devices are provided which include supports upon which one or more ion-exchange materials can be disposed for purifying a sample. In various embodiments, the supports include a plurality of deformable members, for example, petal-shaped purification members, that provide binding sites for ion-exchange material and optionally biochemical species, chemicals, salts, or other materials. An apparatus and method are also provided for the insertion and removal of the purification members into respective wells of a multi-well microplate.

    摘要: The invention provides compositions, methods and kits for high speed, high resolution of analytes by capillary electrophoresis starting with uncoated capillaries. The compositions comprise a sieving component, comprising a non-crosslinked acrylamide polymer, and a surface interaction component, comprising at least one uncharged and non-crosslinked water-soluble silica-adsorbing polymer. Methods for employing the novel compositions in capillary electrophoresis are provided. Kits comprising the novel compositions for use in the novel methods are also provided.

    摘要: The present teachings relate to systems and methods for separation of substances such as cells, nucleic acids, and carbon nanotubes. The substances are combined with a separation medium in a liquid sample cavity, for example a microchannel, and transit through the separation by optically activated dielectrophoretic forces. The substances are advantageously labeled and visualized using a microscope and camera.
