  • Patent number: 10138517
    Abstract: An array of transportable particle sets is used in a microfluidic device for performing chemical reactions in the microfluidic device. The microfluidic device comprises a main channel and intersecting side channels, the main channel and side channels forming a plurality of intersections. The array of particle sets is disposed in the main channel, and the side channels are coupled to reagents. As the particle sets are transported through the intersections of the main channel and the side channels, reagents are flowed through the side channels into contact with each array member (or selected array members), thereby providing a plurality of chemical reactions in the microfluidic system.

  • Patent number: 7566538
    Abstract: Nucleotides and nucleotide analogs are used in various sequencing by incorporation/sequencing by synthesis methods. Nucleotide analogs comprising 3?-blocking groups are used to provide reversible chain-termination for sequencing by synthesis. Typical blocking groups include phosphate groups and carbamate groups. Fluorescent nucleotides are used to perform sequencing by synthesis with detection by incorporation of the fluorescently labeled nucleotide, optionally followed by photobleaching and intercalating dyes are used to detect addition of a non-labeled nucleotide in sequencing by synthesis with detection by intercalation. Microfluidic devices, including particle arrays, are used in the sequencing methods.

  • Patent number: 7521186
    Abstract: Sieving mediums comprising less than about 0.5% polymer, less than about 0.4% polymer, and 0.35% polymer or less are used to perform nucleic acid separations and PCR. The low polymer concentration does not inhibit PCR reactions and is sufficient for performing nucleic acids separations. Microfluidic devices are used to perform nucleic acids separations and PCR reactions in the sieving mediums described.
