Abstract: Provided herein are methods of detecting nucleic acids. The nucleic acid of interest may be detected by using Cas endonuclease to degrade substantially all nucleic acid in a sample except for the nucleic acid of interest, leaving the nucleic acid of interest isolated and amenable to detection. In related methods, Cas endonuclease complexes are used to protect the nucleic acid of interest while unprotected nucleic acid is digested, e.g., by exonuclease, after which the isolated nucleic acid of interest is detected.

Abstract: The invention provides methods of isolating a target nucleic acid in a sample. A primer is hybridized to the target. A polymerase and modified nucleotide resistant to nuclease degradation are used to extend the primer to create a modified polynucleotide. The sample is exposed to a nuclease, thereby isolating the modified polynucleotide. Optionally, the target nucleic acid may be further protected by binding a protein in a sequence specific manner to one end of the target nucleic acid to create a protected target nucleic acid resistant to nuclease degradation. Thus, after exposing the sample to a nuclease, the modified polynucleotide and protected target nucleic acid are isolated.

Abstract: The invention provided methods and devices for performing sequential, regulated multiplex reactions in a single tube without the addition or removal of contents from the tube.

Abstract: The invention provides methods for determining the mutation burden of a tumor by assaying tumor DNA that is representative of genetic loci that are themselves representative of genetics of the tumor. The assayed tumor DNA may be itself agnostic as to loci, so long as it is representative of loci that are representative of tumor mutation burden. The invention provides for assays in which the tumor DNA being sequenced or tested can be something other than, and possibly less than, a full panel of oncogenes that is expected to stand for a tumor's mutational load.

Abstract: A glass manufacturing apparatus includes an enclosure including an interior area and a vessel positioned at least partially within the interior area of the enclosure. The vessel includes a trough and a forming wedge including a pair of downwardly inclined surfaces that converge at a root of the vessel. A draw plane extends from the root of the vessel through an opening of the enclosure in a draw direction. The apparatus includes a thermal shield moveable along an adjustment direction extending perpendicular to the draw plane. The thermal shield includes a non-metallic outer shell and a thermal insulating core. Additionally, methods of manufacturing a glass ribbon with the glass manufacturing apparatus are provided.

Abstract: The invention provides methods for detecting small mutations and structural alterations in DNA by using binding proteins to protect those features while digesting unprotected DNA in a sample. To detect small mutations, a protein that binds exclusively to the mutation of interest, and not to wild-type, is used. For structural alterations, binding proteins are used that flank a breakpoint of the alteration. After digestion of unbound, unprotected nucleic acid in the sample, the mutation- or breakpoint-containing segment remains as an isolated DNA fragment. The sample is then assayed to detect any fragment of DNA and the detection of the fragment indicates the presence of the mutation or breakpoint in the subject.

Abstract: The invention provides methods of isolating a target nucleic acid in a sample. A polynucleotide region flanking a target nucleic acid may be modified by polymerase extension using modified nucleotides resistant to nuclease degradation to create a modified polynucleotide. Alternatively, an oligonucleotide including the modified nucleotides may be ligated to those regions to create the modified polynucleotide. The sample is exposed to a nuclease, thereby isolating the modified polynucleotide and the target nucleic acid. In other alternatives, terminal phosphates may be removed from a desired portion of a polynucleotide with a double-stranded break to create a modified polynucleotide that is resistant to nuclease degradation, or an epigenetic-binding moiety may be bound to a polynucleotide sequence within or flanking target nucleic acids to sterically inhibit nuclease degradation of the target nucleic acids.

Abstract: Methods and kits are provided that are useful as quality controls for gene editing tools. When a gene editing process is proposed for some subject nucleic acid, the gene editing process may be performed on a representative sample—a sample that represents the subject nucleic acid. Off-target effects may be measured and shown for the representative sample to show a prospective rate of off-target activity were the gene editing process to be performed on the subject nucleic acid.
