  • Patent number: 8506908
    Abstract: An electrochemical detection system having a disposable cartridge capable of performing a plurality of assay protocols is disclosed. The cartridge includes a blister pack for the long-term storage and controlled release of multiple reagents. The blister pack is bonded to and operatively associated with a fluidic backbone for providing the fluid pathways, storage capacity, and fluid control functions for performing multiple assay protocols. The cartridge further includes a plurality of sensors having a multiple electrode arrangement in operative association with a respective flow cell defined by the fluidic backbone. After the user has transferred a sample into the cartridge and engaged the cartridge to the reader, the reader operatively interfaces with the cartridge such that different assay protocols may be simultaneously performed in isolation from one another inside the cartridge. The reader may be one of many readers that operatively communicate data to a remote server for processing.

  • Publication number: 20070059781
    Abstract: The invention relates to one or more size-based separation modules adapted to increase a concentration of a first analyte in a sample by at least 10,000 fold, wherein said first analyte has an initial concentration in said sample of less than 1×10?3 analytes/?L, and an analyzer for analyzing said first analytes in an enriched medium.

  • Publication number: 20070026381
    Abstract: The invention features devices and methods for the deterministic separation of particles. Exemplary methods include the enrichment of a sample in a desired particle or the alteration of a desired particle in the device. The devices and methods are advantageously employed to enrich for rare cells, e.g., fetal cells, present in a sample, e.g., maternal blood and rare cell components, e.g., fetal cell nuclei. The invention further provides a method for preferentially lysing cells of interest in a sample, e.g., to extract clinical information from a cellular component, e.g., a nucleus, of the cells of interest. In general, the method employs differential lysis between the cells of interest and other cells (e.g., other nucleated cells) in the sample.

  • Publication number: 20060194264
    Abstract: This invention provides methods and apparatus for detecting and quantifying particulate matter suspended in a fluid. Specifically, the invention provides an integrated, affinity-binding based, analytical system comprising a platform for performing an affinity-binding based assay for specifically binding particulates including microbial cells, and a detection means for detecting the particulates specifically bound to a defined surface or chamber comprising the platform. Methods for using the analytical systems of the invention are also provided.

  • Publication number: 20060121624
    Abstract: The systems and methods herein involve the use of an automated, high-throughput system that utilizes pressure to transfer a fluid medium containing an analyte. In preferred embodiments, the sample is delivered to an analytical device. The sample can comprise one or more analytes, e.g., solvents, solutes, or particles, including rare cells. The systems are designed to minimize contact with potentially hazardous, fragile, or valuable samples. The systems allow for the dilution, mixing, and introduction of the fluid medium to an analytical device, followed by possible further analysis or sample manipulation. The systems and methods herein allow for partial or substantially complete depletion of a sample container to avoid wasting rare analytes or prevent retention of desired material in a first container.

  • Publication number: 20050266433
    Abstract: The present invention features a new and useful magnetic device and methods of its use for isolation, enrichment, and purification of cells, proteins, DNA, and other molecules. In general the device includes magnetic regions or obstacles to which magnetic particles can bind. The chemical groups, i.e., capture moieties, on the surface of the magnetic particles may then be used to bind particles, e.g., cells, or molecules of interest from complex samples, and the bound species may then be selectively released for downstream collection or further analysis.
