Patents by Inventor Guoyan Luan

Guoyan Luan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9157112
    Abstract: Nucleic acid detection probes that comprise a pair of complementary, fluorophore/quencher labeled oligonucleotides, one of which is shorter than the other, are able to detect single-stranded and double-stranded targets in hybridization reactions and amplification reactions with real-time detection. Double-stranded probes of equal length are useful in PCR amplification reactions with real-time detection.
    Type: Grant
    Filed: August 11, 2010
    Date of Patent: October 13, 2015
    Assignee: Quandx, Inc.
    Inventors: Qingge Li, Jixuan Liang, Guoyan Luan

  • Patent number: 7799522
    Abstract: Double-stranded nucleic acid hybridization probes comprise a longer strand perfectly complementary to a preselected target sequence in an assay and a shorter second strand complementary to the longer strand. The strands are labeled with interactive labels such as a fluorophore and a quencher. The probes may be used in real-time amplification assays to distinguish among alleles.
