  • Patent number: 11933759
    Abstract: An apparatus includes a body portion that defines a reservoir and a set of substantially flexible capillaries. The set of substantially flexible capillaries are fixedly coupled to the body portion and in fluid communication with the reservoir. A connector is configured to be coupled to the body portion to be in fluid communication with the reservoir and the set of substantially flexible capillaries. The connector is further configured to be coupled to a vacuum source. The apparatus is arranged such that at least a part of the body portion is electrically conductive. Methods for separating and detecting an analyte from a biological sample with the apparatus are also provided. For example, methods for separating and detecting one or more proteins from a cellular lysate or a purified protein are also provided.

  • Publication number: 20220260525
    Abstract: A system for assaying a biological sample for a presence of a target analyte includes an assaying device and a computer controller. The assaying device includes a housing, a receptacle disposed in the housing, and a source of activation energy. The receptacle is configured to accept an electrophoresis cell. The electrophoresis cell has a recess area configured to accept a chip configured to accept the biological sample. The chip includes a polymeric separation medium with activatable functional groups that covalently bond to the target analyte when activated. The source of activation energy is configured to supply activation energy to activate the activatable functional groups. The computer controller is operably coupled to the source of activation energy and is configured to activate the source of activation energy to direct an application of activation energy to the polymeric separation medium to activate the activatable functional groups.

  • Publication number: 20220236221
    Abstract: Embodiments described herein relate to single-channel free-flow electrophoresis devices or apparatuses, and methods for separating and collecting analytes of interest from a sample by sequentially adjusting the pH value of the electrolyte buffers and separating the analyte of interest according to the corresponding isoelectric points of the analyte of interest. The method includes flowing a sample through a single center channel, applying an electric field perpendicular to a flow direction of the sample via an anolyte channel and a catholyte channel that are parallel to the center channel, and then collecting a fraction of the analyte of interest in accordance with their respective isoelectric points.

  • Patent number: 6870185
    Abstract: Structures and methods that facilitate integration and/or isolation of various functions in a microchip system are disclosed. In one embodiment, the integration of the functions is by a multi-chip, sliding linear valve approach. The chips are in continued physical contact. In a second embodiment, the chips are separated and rejoined when they are moved to the preferred position. Surface coating of the joining edges helps prevent leakage and keeps liquid in the capillary channels for both embodiments. Another embodiment relates to miniature valves. Several designs were disclosed, including the linear, edge-contact sliding valve approach. Method to fabricate very small, high aspect ratio holes in glass was also disclosed, which facilitates the above embodiments.

  • Publication number: 20040017981
    Abstract: A capillary connector having one or more capillary tubes entering a first end and terminating with an open end at a level face on the opposite side of the connector. The face is held by a coupler and brought into a biased abutment such that the open capillary ends are in fluid communication with the ends of microchannels on an abutting surface. These microchannel ends may be capillary tube ends from a second capillary connector or may be openings of microchannels on a substrate. The connector may be a fiber-optic connector modified to hold capillary tubes. Alternatively, the connector may be a substrate having microchannels extending through the substrate and terminating at a level face on the substrate. The coupler may receive the capillary tube, which passes through the coupler. This coupler may be attached to a substrate surface to allow the capillary connector to be joined to the substrate.
