摘要: The present application provides polynucleotides comprising 5′-tails with sequence segments useful for the detection of target nucleic acid sequences, and methods for their use in detecting target nucleic acids. The polynucleotides are used to amplify a subsequence of a target nucleic acid in the presence of one or more ribonucleotides. The ribonucleotides are incorporated into amplification products at regular intervals complementary to the 5′-tail sequence segments. Cleavage of amplification products at the bond immediately 3′ to incorporated ribonucleotides produces detectably distinct fragments indicative of the presence or absence of a target nucleic acid.

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 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.

摘要: The present invention provides reaction mixtures that include blocked oligonucleotides comprising 2′-terminator nucleotides. The blocked oligonucleotides are rendered extendible when the 2′-terminator nucleotides are removed from the oligonucleotides, e.g., via pyrophosphorolysis. The reaction mixtures can be used in various nucleic acid polymerization and/or amplification assays, among many other applications. In addition to reaction mixtures, the invention also provides related methods and reaction mixtures.

摘要: Method of obtaining N-terminal methionine-free proteins are described. The methods employ a novel enzyme, E. coli methionine aminopeptidase either in vitro or in vivo. For in vivo application, plasmid-borne DNA encoding the peptidase is transformed into a bacterial host which produces the desired protein.
