    摘要: The present invention is directed to methods of generating a signal indicative of the presence of a target nucleic acid in a sample by forming a cleavage structure comprising duplex and single-stranded nucleic acid by incubating a sample comprising a target nucleic acid with a thermostable nucleic acid polymerase substantially lacking 5′ to 3′ exonuclease activity and cleaving said cleavage structure with a thermostable Fen nuclease lacking 5′ to 3′ synthetic activity to generate a signal.

    摘要: The invention relates to methods and systems (e.g., computer systems and computer program products) for determining the biological function of uncharacterized cellular constituents, particularly genes and gene products, by using “response profiles,” i.e., measurements of pluralities of cellular constituents in cells having a modified gene or gene product, as phenotypic markers for the gene or gene product. Methods are provided for clustering such response profiles so that similar or correlated response profiles are organized into the same cluster. The invention also provides databases or “compendiums” of response profiles to which the response profile of an uncharacterized gene or gene product can be compared. In one embodiment, steps of the methods comprise comparing the measured response profiles to response profiles stored in the databases or compendiums, and determining the biological function of the response profiles in the databases that are most similar to the measured response profiles.

    摘要: One-step RT-PCR methods, compositions and kits for the detection and quantification of small RNAs in a sample are disclosed. The one-step RT-PCR approach involves polyadenylation of a small RNA followed by reverse transcription with a first primer containing a poly(T) sequence and at least two 3′ nucleotides complementary to the 3′ terminal end nucleotides of the small RNA, to produce a cDNA. This may be followed by PCR amplification using the same first primer as the revere primer and a second, forward primer in which a portion of its sequence is complementary to the 3′ terminal end of the cDNA. This may be then followed by detection and/or quantification of the amplified product.
