Abstract: The present invention relates to a method of sequencing DNA, based on the detection of base incorporation by the release of pyrophosphate (PPi) and simultaneous enzymatic nucleotide degradation.
Abstract: The present invention provides a method of identifying a base at a target position in a single-stranded sample DNA sequence wherein an extension primer, which hybridizes to the sample DNA immediately adjacent to the target position, is provided and the sample DNA and extension primer are subjected to a polymerization reaction in the presence of a deoxynucleotide or dideoxynucleotide, whereby the deoxynucleotide or dideoxynucleotide will only become incorporated and release pyrophosphate if it is complementary to the base in the target position. Release of pyrophosphate is detected enzymatically and pyrophosphate detection enzyme(s) are included in the polymerization step.
Abstract: The present invention provides methods for assessing cardiovascular status in an individual, which comprise determining the sequence at one or more polymorphic positions within the human genes encoding angiotensin converting enzyme (ACE), angiotensinogen (AGT), and/or type 1 angiotensin II receptor (AT1). The invention also provides isolated nucleic acids encoding ACE, AGT, and AT1 polymorphisms, nucleic acid probes that hybridize to polymorphic positions, kits for the prediction of cardiovascular status, and nucleic acid and peptide targets for use in identifying candidate cardiovascular drugs.
