The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

The present invention provides oligonucleotide primers, compositions, and kits containing the same for rapid identification of viruses that cause viral hemorrhagic fevers by amplification of a segment of viral nucleic acid followed by molecular mass analysis.

The present invention relates in one aspect to a method for analyzing the frequency of interaction of a target nucleotide sequence with one or more nucleotide sequences of interest (eg. one or more genomic loci) comprising the steps of: (a) providing a sample of cross-linked DNA; (b) digesting the cross-linked DNA with a primary restriction enzyme; (c) ligating the cross-linked nucleotide sequences; (d) reversing the cross linking; (e) optionally digesting the nucleotide sequences with a secondary restriction enzyme; (f) optionally ligating one or more DNA sequences of known nucleotide composition to the available secondary restriction enzyme digestion site(s) that flank the one or more nucleotide sequences of interest; (g) amplifying the one or more nucleotide sequences of interest using at least two oligonucleotide primers, wherein each primer hybridises to the DNA sequences that flank the nucleotide sequences of interest; (h) hybridising the amplified sequence(s) to an array; and (i) determining the frequency of interaction between the DNA sequences.

Method for amplification, alone or in further combination with detection or detection and quantitation, of RNA from fusion gene variants, method of distinguishing same, and oligonucleotide primers and probes and kits for use in the methods.

Methods of amplifying a target nucleic acid whereby the target nucleic acid is amplified in the presence of a deoxyribonucleotide triphosphate, a DNA polymerase having strand displacement activity, at least one chimeric oligonucleotide primer, at least one upstream block oligonucleotide and a RNase H; wherein the chimeric oligonucleotide primer contains a ribonucleotide positioned at the 3′-terminus; wherein the upstream block oligonucleotide is capable of annealing to a region 3′ to a portion in the nucleic acid as the template to which the chimeric oligonucleotide primer anneals; and compositions and kits thereof.
