  • Patent number: 11262330
    Abstract: An electrophoresis apparatus is generally disclosed for sequentially analyzing a single sample or multiple samples having one or more analytes in high or low concentrations. The apparatus comprises a relatively large-bore transport capillary which intersects with a plurality of small-bore separation capillaries and includes a valve system. Analyte concentrators, having antibody-specific (or related affinity) chemistries, are stationed at the respective intersections of the transport capillary and separation capillaries to bind one or more analytes of interest. The apparatus allows the performance of two or more dimensions for the optimal separation of analytes. The apparatus may also include a plurality of valves surrounding each of the analyte concentrators to localize each of the concentrators to improve the binding of one or more analytes of interest.

  • Patent number: 11198118
    Abstract: The present invention relates to an immunoaffinity device for capturing, isolating and purifying one or more analytes of interest present at high or low concentration in simple or complex matrices. The device is designed as an integrated modular unit that includes one or more analyte concentrator-microreactor devices anchored into a T-shaped support box, which is built-in or connected to a interchangeable cartridge-cassette of a capillary electrophoresis or liquid chromatography apparatus for the isolation, enrichment, derivatization, separation and characterization of small molecules and polymeric macromolecules, primarily protein and peptide biomarkers. The integrated modular unit is also designed to perform metabolic or bioactivity studies.

  • Patent number: 9146234
    Abstract: A disease detection system which includes an electrophoresis apparatus and a biomarker detector. The apparatus includes: (a) a transport passage; (b) a plurality of separation passages, each of the separation passages having an overlapping portion that overlaps the transport passage; and (c) a different biomarker concentrator in each of the overlapping portions and which concentrates at least one different biomarker from a specimen from an animal introduced into the transport passage. A plurality of the different biomarkers is associated with at least one predetermined disease, such as diabetes, heart disease or cancer. The detector detects the presence of the different biomarkers which were concentrated by the biomarker concentrators and delivered to the biomarker detector via the separation passages. First and second sets of the biomarker concentrators can be associated with respective first and second predetermined diseases and the user can determine which set will be used in each procedure.

  • Patent number: 8865075
    Abstract: The present invention relates to an immunoaffinity device for capturing one or more analytes present at high or low concentrations in simple or complex matrices. The device is designed as a modular, multi-task immunoaffinity device secured to a peripheral box and connected to capillary electrophoresis or liquid chromatography for the isolation, enrichment, separation and identification of polymeric macromolecules, primarily protein biomarkers. In one embodiment, two devices are coupled in-tandem to perform separately and sequentially microreactions and concentrations of proteins. In this embodiment, biological samples containing proteins can be subjected to proteolytic processing in the first device, and the resulting peptides subjected to selective purification and concentration in the second device.
