Abstract: The invention relates to a method for the quantification of one or more nucleic acids in a sample, for example: making a sample available which contains at least one nucleic acid to be quantified, adding an oligonucleotide probe, the oligonucleotide probe comprising a sequence which can specifically hybridize to the nucleic acid to be quantified or to a common sequence of the nucleic acids to be quantified, incubating the sample under conditions which allow the hybridization of the oligonucleotide probe to the nucleic acid(s) to be quantified, incubating the sample under conditions which allow the extension of hybridized probes, the nucleic acid(s) serving as a template in each case, removing the non-hybridized probes from the sample and quantifying the hybridized oligonucleotide probes to measure the quantity of the nucleic acid(s) to be quantified. The invention also relates to a kit for carrying out said method.

Abstract: Novel thermostable chimeric nucleic acid polymerases and methods for their generation and use are disclosed. It is shown that these chimeric nucleic acid polymerases, such as DNA polymerases, can be constructed using enzymatically active domains, isolated from different proteins or chemically synthesized. It is demonstrated that chimeric nucleic acid polymerases of the present invention possess the chemical and physical properties of their component domains (e.g., exonuclease activity, thermostability) and that the chimeric polymerases are thermostable.

Abstract: Novel compositions and methods useful for the generation of nucleic acids from a ribonucleic acid template and further nucleic acid replication are disclosed. It is shown that the generation and amplification of nucleic acids by methods that utilize two or more different polymerases, such as reverse transcriptase-polymerase chain reaction (RT-PCR), are dramatically more sensitive and efficient in the presence of a homopolymeric nucleic acid. Homopolymeric nucleic acids have been found to reduce or negate the inhibitory effect reverse transcriptases have on DNA polymerase activity. It is demonstrated that this inhibition-relieving effect of homopolymeric nucleic acids is general in nature; independent of the chemical species of homopolymer used, or the chemical composition of the polymerization reaction mixture.
