  • Nucleic acid detection or quantification method using mask oligonucleotide, and device for same
    Patent number: 11193162
    Abstract: Very simple, highly sensitive detection or quantification of target nucleic acids of interest has been achieved by: hybridizing mask oligonucleotides to regions in a single-stranded region of a nucleic acid to be assayed between which a region to be hybridized by an oligonucleotide probe is positioned, thereby opening the probe-hybridizing region and keeping the single-stranded region of the target nucleic acid stable, and then subjecting this nucleic acid having the single-stranded region to nucleic acid chromatography.
    Type: Grant
    Filed: January 29, 2015
    Date of Patent: December 7, 2021
    Assignee: Fuso Pharmaceutical Industries, Ltd.
    Inventors: Norihiko Sugimoto, Souji Eda, Masahiro Asakura, Kanako Abe, Hirotsugu Uehara, Kazumasa Kamei, Yoshihiko Uesaka, Yuichi Oku, Yusuke Shibahara
