    摘要： Aspects of the present invention provide a method and apparatus of generating a calibration matrix for a spectral detector instrument. A calibration plate contains one or more dye mixtures in each well of the calibration plate at known absolute concentration. From the calibration plate, aspects of the present invention are used to prepare a concentration matrix based on the dyes used in the assay and the different dye mixtures used in the calibration plate. An excitation source exposes the calibration plate causing the spectral species in each of the wells to fluoresce. The emission spectra for the different dye mixtures of dyes as gathered by the spectral detector instrument at different points in the range of spectra is used to generate a spectral matrix. Bilinear calibration is performed on the concentration matrix and the spectral matrix as to determine a calibration matrix relating spectra directly to absolute concentrations.

    摘要： Disclosed are methods for detecting or quantifying one or more target polynucleotide sequences in a sample. In one aspect, a sample is contacted with first and second probe pair that are capable of hybridizing to a selected target sequence and a corresponding complementary sequence, respectively. Probe cleavage and ligation results in the formation of ligation products which can be generated in an exponential fashion when the target sequence and/or complement are present in the sample. In another embodiment, a single probe pair can be used to form ligation product in a linear fashion from a complementary template. Reagents and kits are also disclosed.

    摘要： The present teachings provide methods, compositions, and kits for reverse transcribing and amplifying small nucleic acids such as micro RNAs. High levels of multiplexing are provided by the use of a zip-coded stem-loop reverse transcription primer, along with a PCR-based pre-amplification reaction that comprises a zip-coded forward primer. Detector probes in downstream decoding PCRs can take advantage of the zip-code introduced by the stem-loop reverse transcription primer. In some embodiments, further amplification is achieved by cycling the reverse transcription reaction. The present teachings also provide compositions and kits useful for performing the reverse transcription and amplification reactions described herein.

    摘要： Disclosed is a method for determining the number of repeat units in a repeat region of a target nucleic acid. In a first aspect, the method of the invention includes the steps of annealing a primer to a target nucleic acid; performing a first primer extension reaction using a first primer extension reagent; separating the target-primer hybrid and unreacted first primer extension reagent; performing a second primer extension reaction using a second primer extension reagent, wherein at least one of the first or second primer extension reagents includes an extendible nucleotide having a label attached thereto; separating the target-primer hybrid from unreacted second primer extension reagent; measuring a signal produced by the label; treating the label so as to render the label undetectable; and repeating the above steps until the signal is substantially less than a signal detected in a previous cycle.
