  • Patent number: 8637658
    Abstract: Bis-diazo, triaryl and aryldiazo-N-arylphenazonium quencher moieties, substituted with electron-withdrawing and electron-donating substituents which induce polarity in the delocalized aryl/diazo ring systems, are useful as labels when attached to biomolecules such as polynucleotides, nucleosides, nucleotides and polypeptides. The quencher moieties are non-fluorescent and accept energy transfer from fluorescent reporter labels by any energy-transfer mechanism, such as FRET. Fluorescence quencher compositions are useful in preparing quencher labeled biomolecules for various molecular biology assays based on fluorescence detection.
    Type: Grant
    Filed: September 27, 2012
    Date of Patent: January 28, 2014
    Assignee: Applied Biosystems, LLC
    Inventors: Gregory J. Ewing, Khairuzzaman Bashar Mullah, Ronald Graham
  • Patent number: 8637247
    Abstract: The present disclosure relates to methods of identifying target nucleic acids by using coded molecules and its analysis by translocation through a nanopore. Generally, coded molecules are subject to a target polynucleotide dependent modification. The modified coded molecule is detected by isolating the modified coded molecules from the unmodified coded molecules prior to analysis through the nanopore or by detecting a change in the signal pattern of the coded molecule when analyzed through the nanopore.
