Abstract: The invention relates to compositions and methods for multiplex decoding of microsphere array sensors.

Abstract: The invention is directed to a variety of multiplexing methods used to amplify and/or genotype a variety of samples simultaneously.

Abstract: The invention relates to DNA sequencing by synthesis techniques, including those utilizing the detection of pyrophosphate (PPi) generated during the DNA synthesis reaction (pyrosequencing). The methods and compositions utilize biosensor arrays comprising microspheres distributed on a surface.

Abstract: The present invention relates to detection or genotyping (or other sample analysis) of target nucleic acids following immobilization of the target nucleic acids onto a surface. The target nucleic acids can be re-used multiple times, thus conserving sample materials and simplifying sample preparation.

Abstract: The invention relates to compositions and methods for decoding microsphere array sensors.

Abstract: The invention relates to the use of a computer system to compare images generated from a randomly ordered array. This system preserves the relative position of each site within the array so that the same site can be compared in different images.

Abstract: A holder for an array of bundles containing multiple fiber optic strands provides a pattern of openings into which one each of each bundle is fit. The openings may (but need not) penetrate the full holder thickness to permit working with bundles from either bundle end. In one embodiment the holder thickness equals the bundle length, and the holder is sized similarly to a microscope slide. An alternative embodiment temporarily retains bundles in a desired registration and subjects the retained bundles to molten material such as wax that is allowed to harden around the bundles and become the holder. A modular holder comprises laminates that each contain parallel grooves sized to receive a bundle. A holder for a single bundle includes cooperating grip-like members, one of which is pivotably attached and biased toward the other member. A common form factor may be used for each holder type to facilitate retaining holders in a common docking station.

Abstract: In accordance with the objects outlined above, the present invention provides microfluidic devices for the detection of a target analyte in a sample. The devices comprise a solid support that has any number of modules, including a a sample inlet port and at least one sample handling well comprising a well inlet port and a well outlet port. The device generally further comprises a first microchannel to allow fluid contact between the sample inlet port and the sample handling well. The device also comprises a detection module comprising a substrate with a surface comprising discrete sites, and a population of microspheres comprising at least a first and a second subpopulation, wherein each subpopulation comprises a bioactive agent. The microspheres are distributed on said surface. The detection module also comprises a detection inlet port to receive the sample. The device also comprises a second microchannel to allow fluid contact between the sample handling well and the detection inlet port.
