摘要:
Methods are provided for reducing background signals encountered in nucleic acid hybridization assays and other assays that involve hybridization of a labeled oligomer to its complement. The method is premised on the significant reduction of signal generation that occurs when a quenchable dye-labeled oligomer forms a hybrid complex. In addition, a method is provided for enhancing the detectable signal emitted from an amplification multimer hybridized to an oligomer probe to which a quenchable dye has been conjugated through a linker such that the emission from the dye is not quenched upon hybrid complex formation. Novel oligonucleotide probes are also provided that comprise an oligomer to which has been directly or indirectly through a linker a quenchable dye.

The present invention provides for primer extension reactions, including polymerase chain reactions, in which a polymerase having 3′-5′ exonuclease activity edits a primer that is not fully complementary thereby allowing for amplification and detection of target nucleic acids that may have variability in their sequences.
摘要:
Disclosed are mutant DNA polymerases having improved extension rates relative to a corresponding, unmodified polymerase. The mutant polymerases are useful in a variety of disclosed primer extension methods. The mutant polymerases overcome the inhibitory effects by an intercalating dye. Therefore, the mutant polymerases are useful in a variety of disclosed methods in combination with an intercalating dye. Also disclosed are related compositions, including recombinant nucleic acids, vectors, and host cells, which are useful, e.g., for production of the mutant DNA polymerases.

Disclosed are mutant DNA polymerases having improved extension rates relative to a corresponding, unmodified polymerase. The mutant polymerases are useful in a variety of disclosed primer extension methods. The mutant polymerases overcome the inhibitory effects of a variety of polymerase and reverse transcriptase inhibitors. Therefore, the mutant polymerases are useful in a variety of disclosed methods in the presence of such inhibitors.
