  • 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.

  • Publication number: 20120003648
    Abstract: Disclosed are methods, compositions and kits for amplifying signals for detecting the presence, quantity and/or sequence of nucleic acids and proteins, as well as methods, compositions and kits for increasing the number of such targets simultaneously detectable in a sample. Detection may be, for instance, in vivo, in cellulo or in situ. Amplification of signal is achieved by way of hybridization of nucleic acid label probe systems and structures. Increase in target multiplex capacity is achieved by way of varying the type of labels utilized in the nucleic acid label probe system.

  • Publication number: 20110256536
    Abstract: This invention provides methods, compositions and systems to detect a nucleic acid of interest in a two-stage amplification. The two-stage amplification begins with a first non-enzymatic accumulation of an amplification oligomer that is the target substrate for a second nucleic acid amplification or assay. Two or more amplification oligomers can be used to allow multiplexed amplifications of two or more nucleic acids of interest with deconvolution based on unique detection signals or unique signal locations.

  • Publication number: 20110237449
    Abstract: Methods of capturing two or more nucleic acids simultaneously from a single sample are provided. Different nucleic acids are captured through cooperative hybridization events on a substrate, or different subsets of particles, or at different selected positions on a spatially addressable solid support. Methods described include enrichment and purification of nucleic acids prior to downstream steps including sequencing of target nucleic acids. Compositions, kits, and systems related to the methods are also described.

  • Publication number: 20110223606
    Abstract: This invention provides methods of quantitating nucleic acids from problematic samples, such as aged samples, formalin fixed samples, paraffin embedded samples, samples with aneuploid cells, and cells with fragmented nucleic acids. Methods include techniques to efficiently solubilize the nucleic acids under non-denaturing conditions from preserved clinical samples without resort to organic extractions, to normalize cell counts regardless of aneuploidy, to access the fragmentation state of the nucleic acids, and to provide standard curves for degraded nucleic acid samples.
