  • Publication number: 20080145898
    Abstract: The present teachings provide methods and compositions for sequencing one or more target nucleic acids. High levels of multiplexing are provided by the use of an emulsion PCR comprising primer-immobilized beads. The resulting reaction products can be sequenced by any of a variety of mobility-dependent analytical techniques, such as mass spectrometry. In some embodiments, a first collection of amplification products on a first collection of beads are transferred to a second collection of beads. In some embodiments, a first collection of amplification products on a first collection of beads is amplified in a rolling circle amplification reaction. The present teachings also provide compositions, kits, and devices for performing and sequencing the products of the emulsion amplification reactions as described herein.

  • Publication number: 20080124730
    Abstract: The present teachings provide novel methods, compositions, and kits for detecting siRNA-containing RISCs. In some embodiments, modified siRNA constructs are employed that contain an anti-sense strand and a sense strand, wherein the anti-sense strand comprises a 3? end, wherein the 3? end comprises a fluorophore, and wherein the sense strand comprises a 5? end, wherein the 5? end comprises a quencher. Following transfection, uptake of the anti-sense strand by RISC liberates the fluorescent signal, allowing for detection of siRNA-containing RISCs.

  • Patent number: 7255994
    Abstract: Disclosed are methods and kits for detecting or quantifying one or more target polynucleotide sequences in a sample. Embodiments of the invention employ a first ligation reaction, a subsequent optional amplification reaction, and a second ligation reaction. Embodiments of the invention combine the specificity of both hybridization and ligation reactions along with universal probe polynucleotide sequences to achieve specific and multiplexed detection of a plurality of target polynucleotide sequences.

  • Patent number: 7208278
    Abstract: The present teachings relate to methods, compositions, and kits for detecting one or more target polynucleotide sequences in a sample, and methods compositions and kits for forming concatameric ligation products. In some embodiments of the present teachings, oligonucleotides are hybridized to complementary target polynucleotides and are ligated together to form a concatameric ligation product. In some embodiments of the present teachings, the concatameric ligation product can be amplified, and the identity and quantity of the target polynucleotides determined based on sequence introduced in the ligation reaction. Some embodiments of the present teachings provide methods for removing unligated probes from the reaction mixture. Some embodiments of the present teachings provide for highly multiplexed detection, identification, and quantification of a plurality of target polynucleotides using a variety of analytical procedures.
