Abstract: The present invention is directed to compositions and methods useful for the amplification of nucleic acid molecules by reverse transcriptase-polymerase chain reaction (RT-PCR). Specifically, the invention provides compositions and methods for the amplification of nucleic acid molecules in a simplified one- or two-step RT-PCR procedure using combinations of reverse transcriptase and thermostable DNA polymerase enzymes in conjunction with sulfur-containing molecules or acetate-containing molecules (or combinations of such sulfur-containing molecules and acetate-containing molecules), and optionally bovine serum albumin. The invention thus facilitates the rapid and efficient amplification of nucleic acid molecules and the detection and quantitation of RNA molecules. The invention also is useful in the rapid production and amplification of cDNAs which may be used for a variety of industrial, medical and forensic purposes.

Abstract: The present invention is directed to compositions comprising mixtures of reagents, including thermostable enzymes (e.g., thermostable DNA polymerases), buffers, cofactors and other components, suitable for immediate use in nucleic acid amplification or sequencing techniques without dilution or addition of further components. The compositions contain no stabilizing agents (e.g., glycerol or serum albumin) and unexpectedly maintain activity for extended periods of time upon storage at temperatures above freezing. These compositions are useful, alone or in the form of kits, for nucleic acid amplification (e.g., by the Polymerase Chain Reaction) and sequencing (e.g., by dideoxy or “Sanger” sequencing), or for any procedure utilizing thermostable DNA polymerases in a variety of medical, forensic and agricultural applications. In particular, the compositions and methods are useful for amplifying and sequencing nucleic acid molecules that are larger than about 7 kilobases in size.

Abstract: Compositions and methods are provided that improve the specificity and efficiency of nucleic acid amplification. A binding partner may be bound to a DNA polymerase enzyme where the binding partner substantially inhibits the activity of the polymerase. A second enzyme modifies the binding partner in a manner that relieves the inhibition of the polymerase activity. The activity of the second enzyme may be inhibited in a temperature-sensitive manner such that the second enzyme is active only at elevated temperatures. As a consequence, the polymerase enzyme also is active only when the temperature is elevated.
