摘要:
Embodiments herein provide for methods, compositions and apparati for detection and/or diagnosis of virus types, subtypes and/or strains. In particular embodiments, the virus is an influenza virus. The apparatus may include a microarray with attached capture probes, designed to bind to oligonucleotides capable of binding at least a portion of a nucleic acid sequence of one or more target genes in a broad array of influenza types, subtypes or strains. The compositions may include isolated nucleic acids as capture probes, target sequences and/or tagged label probes, of use for diagnosis and/or detection of influenza virus.
摘要:
The invention provides methods to detect molecular recognition events. The invention also provides methods to detect the presence of or identify a target species based on its interaction with one or more probe species. The methods of the invention are based on amplification of the signal due to each molecular recognition event. The amplification is achieved through photopolymerization, with the polymer formed being associated with the molecular recognition event. In an embodiment, a fluorescent polymer, a magnetic polymer, a radioactive polymer or an electrically conducting polymer can form the basis of detection and amplification. In another embodiment, a polymer gel swollen with a fluorescent solution, a magnetic solution, a radioactive solution or an electrically conducting solution can form the basis of detection and amplification. In another embodiment, sufficient polymer forms to be detectable by visual inspection.

Embodiments of the present invention relate to compositions, methods and apparatus for detection of antiviral agent resistance or sensitivity of a virus. In some embodiments, antiviral agent resistance or sensitivity of influenza types, such as A, B and C may be identified. In more embodiments, sub-types such as the hemagglutinin (HA) and neuraminidase (NA) of influenza A may be analyzed for antiviral agent resistance or sensitivity. In a particular embodiment, the various strains of influenza virus may be analyzed for resistance or sensitivity using DNA microarray analysis designed to target a gene segment. In various embodiments, a microarray-based assay system with capture and detection (label) probes may be utilized to identify a change in a gene segment that confers resistance or sensitivity to an antiviral agent of an influenza strain.

Embodiments herein provide for methods, compositions and apparatus for detection and/or diagnosis of pathogenic virus lineage and/or strains. In some embodiments, the virus is influenza Type B virus. In other embodiments, an apparatus may include a microarray with attached capture probes, designed to bind to nucleic acid sequences from a single gene in a broad array of influenza strains. In some embodiments, compositions may include isolated nucleic acid sequences of use as capture probes, target sequences and/or label probe sequences, for diagnosis of and/or detection of influenza virus.
