  • Patent number: 10041107
    Abstract: Currently, the circularization of small RNAs is broadly regarded as an obstacle in ligation-related assays and explicitly avoided while short lengths of linear RNA targets is broadly recognized as a factor limiting use of conventional primers in PCR-related assays. In contrast, the disclosed invention capitalizes on circularization of small RNA targets or their conjugates with oligonucleotide adapters. The circular RNA templates provide amplification of the target sequences via synthesis of multimer nucleic acids that can be either labeled for direct detection or subjected to PCR amplification and detection. Structure of small circular RNAs and corresponding multimeric nucleic acids provide certain advantages over current methods including flexibility in design of conventional RT and PCR primers as well as use of 5?-overlapping dimer-primers for efficient and sequence-specific amplification of short target sequences.

  • Patent number: 9809847
    Abstract: Disclosed herein are compositions and methods for the processing, amplification and detection of polynucleotides using target-specific oligonucleotides (TSOs). Hybridization of TSOs to target polynucleotides guides target processing into and purification of small target fragments that then can be amplified and detected with high sensitivity and reproducibility. The method is specifically beneficial for highly degraded polynucleotides found in biological samples.

  • Publication number: 20160215328
    Abstract: Methods, systems and compositions are provided for analyzing one or more nucleic acid molecules. The methods, systems and compositions may comprise one or more target specific-oligonucleotide probes (TSPs). The TSPs may hybridize to nucleic acid molecules that are less than or equal to 200 nucleotides in length. The nucleic acid molecules may be small RNA molecules (e.g., miRNA, ncRNA, siRNA, shRNA). The methods, systems and compositions fmd use in a number of applications, for example, isolation of nucleic acid molecules, analysis of low abundance nucleic acid molecules, and/or enrichment of nucleic acid molecules.
