  • Patent number: 10266879
    Abstract: This invention provides compositions, methods, and systems for characterizing, resolving, and quantitating single stranded and double stranded DNA and RNA in-situ. Paired sense and anti-sense probes can signal the presence of double stranded nucleic acids. DNA and RNA can be distinguished in cell and tissue samples by hybridizing with probe sets adapted to highlight differences in these targets in-situ.

  • Publication number: 20120172246
    Abstract: Methods of detecting various types of nucleic acids, including methods of detecting two or more nucleic acids in multiplex branched-chain DNA assays, are provided. Detection assays may be conducted at least in vitro, in cellulo, and in situ. Nucleic acids which are optionally captured on a solid support are detected, for example, through cooperative hybridization events that result in specific association of a label probe system with the nucleic acids. Various label probe system embodiments are provided. Compositions, kits, and systems related to the methods are also described.
