The present invention provides compounds and methods for assaying redox state of metabolically active cells and methods for assaying enzyme activity and/or metabolite level by coupling to redox defining co-factor NAD(P)/NAD(P)H measurement.

Compounds and methods for assaying redox state of metabolically active cells and methods for measuring NAD(P)/NAD(P)H

Processes are disclosed using the depolymerization of a nucleic acid hybrid to qualitatively and quantitatively analyze for the presence of a predetermined nucleic acid. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, speciation, determination of viral load, genotyping, medical marker diagnostics, and the like.

Detection of nucleic acid hybrids

Processes are disclosed using the depolymerization of a nucleic acid hybrid to qualitatively and quantitatively analyze for the presence of predetermined nucleic acid target sequences using a multiplex assay format. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, speciation, genotyping, medical marker diagnostics, and the like.

Multiplex method for nucleic acid detection

Processes are disclosed using the depolymerization of a nucleic acid hybrid to qualitatively and quantitatively analyze for the presence of a predetermined endogenous nucleic acid. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, speciation, determination of viral load, genotyping, medical marker diagnostics, and the like.

This invention discloses methods, compositions and kits for the detection of extremely low levels of nucleic acid, cells and cellular material in biological samples. The nucleic acid detection systems utilize either the pyrophosphorolysis reaction catalyzed by various polymerases or nuclease digestion coupled with pyrophosphorylation catalyzed by phosphoribosylpyrophosphate synthetase to produce either deoxyribonucleoside triphosphates or ribonucleoside triphosphates. dNTPs are transformed to ATP by the action of nucleoside diphosphate kinase. The ATP produced by these reactions may be detected by luciferase or NADH based detection systems. If more sensitive detection is required, schemes for the amplification of NTPs and dNTPS are provided. A detection system for cells or cellular material in a sample is provided wherein AMP and a high energy phosphate donor added to a sample are converted to ATP by the action of endogenous enzymes, followed by detection of the ATP.

Nucleic acid detection

The detection of enhanced, targeted predetermined nucleic acid sequences in nucleic acid target hybrids, and the various applications of target nucleic acid enhancement are disclosed.

Deploymerization method for nucleic acid detection of an amplified nucleic acid target

Processes are disclosed using the depolymerization of a nucleic acid hybrid to qualitatively and quantitatively analyze for the presence of a predetermined exogenous nucleic acid. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, determination of viral load, genotyping, medical marker diagnostics, and the like.

Exogenous nucleic acid detection

Mass spectrometric, absorbance spectroscopic and fluorescence spectroscopic processes are disclosed to detect the depolymerization of a nucleic acid hybrid in order to qualitatively and quantitatively assay for the presence of a predetermined nucleic acid target. Applications of those processes include the detection of single nucleotide polymorphisms, identification of single base changes, speciation, determination of viral load, genotyping, medical marker diagnostics, and the like, including multiplexed assays.

Analytical methods and materials for nucleic acid detection

This invention discloses methods for detecting specific nucleic acid sequences, interrogating the identity of a specific base within a sequence, and assaying endonuclease and exonuclease activity. DNA or RNA probes are hybridized to target nucleic acid sequences. Probes that are complementary to the target sequence at each base are depolymerized, while probes which differ from the target at the interrogation position are not depolymerized. The nucleic acid detection systems utilize the pyrophosphorolysis reaction catalyzed by various polymerases to produce deoxyribonucleoside triphosphates or ribonucleoside triphosphates. dNTPs are transformed to ATP by the action of NDPK. The ATP produced by these reactions is detected by luciferase or NADH based detection systems.
