摘要:
The present invention relates to compositions and methods that allow the manipulation of the catalytic activity of multi-component nucleic acid complexes. Further, the invention provides methods which use these compositions and methods to create molecular sensors, molecular switches, and/or modulators or propagators of autocatalytic self-replicating cascades and other iterative processes. More particularly, the invention relates to compositions allowing self-assembly of active and inactive multicomponent nucleic acid complexes, methods of making such compositions, and methods for use.

The present invention relates to methods and means for the evaluation of HIV replicative capacity in a given environment. In particular, the invention provides a growth competition assay that can determine relative viral fitness using a recombinant tagged HIV-1 virus system. The methods rely on plasmid vectors, amplicons, primers and probes, and the generation of replication-competent viruses therefrom. Said methods and materials may find use in multiple fields including diagnostics, drug screening, pharmacogenetics and drug development.
摘要:
The present invention relates to methods that utilize multi-component nucleic acid complex (MNA complex) cascades. The MNA complexes may have cleavage or ligase activity. Further, the invention provides cascades which may include one or more DNAzymes. The invention also provides methods which use these cascades for the identification, detection and quantification of targets.
摘要:
The invention concerns a method for the extraction of nucleic acids from biological samples e.g. tissue material or sputum derived from human or animal species and the quantitative detection thereafter of said nucleic acids e.g. in terms of viral load, more specifically RSV viral load detection.
摘要:
The present invention relates to Multicomponent Nucleic Acid Enzymes (MNAzymes) and methods for their use. MNAzymes comprise two or more oligonucleotide components which self-assemble in the presence of one or more MNAzyme assembly facilitator molecules to form a catalytically active structure which may have cleavage, ligase or other enzymatic activity. Compositions for making MNAzymes and collections of MNAzymes are provided, together with uses thereof. Also provided are methods for using MNAzymes for the detection, identification and/or quantification of one or more targets. The methods can be practiced in solution-based assays or in assays where one or more reaction components are attached to a support structure. The methods allow for multiplexing the MNAzyme detection to detect multiple targets in a single reaction. Also provided are kits for making the compositions, and for practicing the methods provided herein.

摘要:
The present invention relates to compositions and methods for the use of enzymes composed of nucleic acid and/or protein enzymes to generate and amplify a signal indicative of the presence of a target. More particularly, the invention relates to compositions comprising nucleic acid structures that serve as partial or complete enzyme substrates and methods for using these structures to facilitate detection of targets.
