Abstract: Methods for enhancing the binding of oligonucleotide probes to DNA and RNA are disclosed. The methods make use of thermodynamic and kinetic effects to reduce probe mismatches and failure of complementary probes to bind to DNA and RNA templates. Mapping and sequencing of the probed DNA and RNA samples are contemplated herein.
Abstract: Provided are methods and devices for detection of unlabeled nucleic acids. The detection methods are based on change of solubility of hydrophobic probes upon hybridization with a polynucleotide. In one embodiment, the probes are morpholino probes, having a fluorophore attached thereto. The morpholino probes are immobilized on a substrate that has fluorescence quenching functionality.

Abstract: Methods and systems are provided for creating molecular barcodes or indicia for cellular constituents within single cells and for resolving such barcodes or indicia with super resolution technologies such as super resolution microscopy. By this approach, numerous molecular species that can be measured simultaneously in single cells. It has been demonstrated that multiple mRNA transcripts can be labeled with a spatially ordered sequence of fluorophores, and that barcode can be resolved. The methods and systems can be used for genome-wide transcriptional profiling in individual cells by super-resolution barcoding and suggest a general strategy to bring large-scale-omics approach into single cells.

Abstract: The present invention relates to a novel method for detecting a target polynucleotide having a target sequence, comprising hybridizing the target polynucleotide with a probe to form a hybrid; exposing the hybrid to a 5? exonuclease so that the probe in the hybrid is digested and the target polynucleotide is dissociated from the digested probe; repeating the hybridization step and the digestion step; and detecting the digested probes. The presence of the digested probes indicates the presence of the target polynucleotide.

Abstract: Solid support assays using non-standard bases are described. A capture oligonucleotide comprising a molecular recognition sequence is attached to a solid support and hybridized with a target. In some instances, the molecular recognition sequence includes one or more non-standard bases and hybridizes to a complementary tagging sequence of the target oligonucleotide. In other instances, incorporation of a non-standard base (e.g., via PCR or ligation) is used in the assay.

Abstract: Provided are methods of depleting a target nucleic acid from an initial collection of nucleic acids. Aspects of the methods include contacting the initial collection with a nucleic acid guided nuclease specific for the target nucleic acid in a manner sufficient to deplete the target nucleic acid from the initial collection. Depending on a given application, depletion of a target nucleic acid may vary, e.g., where depleting may include cleaving a target nucleic acid in, or selectively separating a target nucleic acid from, the initial collection of nucleic acids. Also provided are compositions and kits for practicing embodiments of the methods.
