    摘要: Methods of preparing nucleic acid from polysaccharide-containing samples for detection by providing one or more glycosidases to the sample to degrade polysaccharides are provided. The nucleic acids can further be extracted from the sample. The method is particularly useful for detecting nucleic acid in samples with high starch content.

    摘要: Methods of determining the presence or amount of a target polynucleotide in a sample are provided. A sample that contains a target polynucleotide, a polynucleotide that may include nucleic acid analogs and that is complementary to a target nucleic acid sequence of the target polynucleotide, and a dye for which the rate of change in an optical property is different in the presence and absence of a target polynucleotide/polynucleotide hybrid are combined to produce a reaction mixture. The rate of change in an optical property of the dye in the reaction mixture is compared to a reference value characteristic of the rate of change in the optical property of the dye in a similar reaction mixture containing a known amount of a polynucleotide/polynucleotide hybrid to determine a relative rate of change in the optical property. The relative rate of change in the optical property of dye in the reaction mixture is correlated with the presence or amount of the specified target polynucleotide in the sample.

    摘要: The present invention relates to methods for detecting the presence or amount of a target polynucleotide. A polynucleotide, target nucleic acid analog, and dye are combined to form a mixture. The optical property of the dye is observed after the mixture is exposed to a stimulating means. Optionally, after the stimulating means is employed, the mixture is compared to a reference value characteristic of the rate of change in the optical property of the dye in a similar mixture containing a known amount of a target polynucleotide/nucleic acid analog hybrid to determine a relative rate of change in the optical property. The change in a property of the mixture after exposure thereof to a stimulating means or the relative rate of change in the optical property of dye in the mixture is correlated with the presence or amount of the specified target polynucleotide in the sample.
