    摘要: The present invention provides labeled nucleic acid amplification oligonucleotides, which can be linear or hairpin primers or blocking oligonucleotides. The oligonucleotides of the invention are labeled with donor and/or acceptor moieties of molecular energy transfer pairs. The moieties can be fluorophores, such that fluorescent energy emitted by the donor is absorbed by the acceptor. The acceptor may be a fluorophore that fluoresces at a wavelength different from the donor moiety, or it may be a quencher. The oligonucleotides of the invention are configured so that a donor moiety and an acceptor moiety are incorporated into the amplification product. The invention also provides methods and kits for directly detecting amplification products employing the nucleic acid amplification primers. When labeled linear primers are used, treatment with exonuclease or by using specific temperature eliminates the need for separation of unincorporated primers. This "closed-tube" format greatly reduces the possibility of carryover contamination with amplification products, provides for high throughput of samples, and may be totally automated.

    摘要: A method for analyzing a target nucleotide sequence which exists in a first state or a different second state which makes the method particularly useful for determining point mutations. The method uses a first polynucleotide which is immobilized on a solid support and which is at least partially complementary to a first segment of the target nucleotide sequence. By means of a series of steps, a product of the first polynucleotide and a further polynucleotide that contains a detectable label can be obtained. When the state to be analyzed occurs in a rare population, amplification can be conducted so that substantially only amplification of the target nucleotide sequence in one of the states is attained. The method can be used to analyze multiple target sequences simultaneously. A kit which can be used in the method is also set forth.

    摘要: A method for normalizing the intensity of G bands in sequencing methods which utilize dITP is presented. The use of dITP normally results in decreased intensities of G bands which occur after A bands, i.e., in the sequence AG. It has been discovered that the use of ddITP in place of ddGTP or in conjunction with ddGTP helps to normalize the intensity of the G bands following A bands. This aids in preventing errors in reading sequencing chromatograms and allows for extended reads of sequencing chromatograms as compared to methods which utilize dITP without the use of ddITP.
