Patent number: 11891663Abstract: The present invention is directed to methods, reagents, kits, and compositions for identifying and quantifying target polynucleotide sequences. A linker probe comprising a 3? target specific portion, a loop, and a stem is hybridized to a target polynucleotide and extended to form a reaction product that includes a reverse primer portion and the stem nucleotides. A detector probe, a specific forward primer, and a reverse primer can be employed in an amplification reaction wherein the detector probe can detect the amplified target polynucleotide based on the stem nucleotides introduced by the linker probe. In some embodiments a plurality of short miRNAs are queried with a plurality of linker probes, wherein the linker probes all comprise a universal reverse primer portion a different 3? target specific portion and different stems. The plurality of queried miRNAs can then be decoded in a plurality of amplification reactions.Type: GrantFiled: August 26, 2020Date of Patent: February 6, 2024Assignee: APPLIED BIOSYSTEMS, LLCInventors: Caifu Chen, Dana Ridzon, Zhaohui Zhou, Kai Qin Lao, Neil A.
