  • Patent number: 11421263
    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.

  • Publication number: 20130157870
    Abstract: The invention generally relates to methods for obtaining a sequence, such as a consensus sequence or a haplotype sequence. In certain embodiments, methods of the invention involve determining an amount of amplifiable nucleic acid present in a sample, partitioning the nucleic acid based upon results of the determining step such that each partitioned portion includes, on average, a subset of unique sequences, sequencing the nucleic acid to obtain sequence reads, and assembling a consensus sequence from the reads.

  • Publication number: 20130117869
    Abstract: The present invention relates to a method for the generation of compact Transcription Activator-Like Effector Nucleases (TALENs) that can efficiently target and process double-stranded DNA. More specifically, the present invention concerns a method for the creation of TALENs that consist of a single TALE DNA binding domain fused to at least one catalytic domain such that the active entity is composed of a single polypeptide chain for simple and efficient vectorization and does not require dimerization to target a specific single double-stranded DNA target sequence of interest and process DNA nearby said DNA target sequence. The present invention also relates to compact TALENs, vectors, compositions and kits used to implement the method.

  • Publication number: 20130085073
    Abstract: A reaction mixture including (a) a nucleic acid having a primer hybridized to a template, (b) nucleotide analogs, wherein the nucleotide analogs have a blocking moiety; (c) a polymerase that is capable of forming an extended primer by adding the nucleotide analogs to the primer, and (d) a deblocking agent that is capable of removing the blocking moiety from the extended primer. Also provided is a method of synthesizing a polynucleotide including sequentially adding a plurality of the different nucleotides analogs to the nucleic acid via several reaction cycles in the reaction mixture, wherein each reaction cycle includes (i) the polymerase adding a nucleotide analog to the nucleic acid to form a transient nucleic acid species comprising a blocking moiety, and (ii) the deblocking agent modifying the transient nucleic acid species to remove the blocking moiety.

  • Publication number: 20130005612
    Abstract: A method for synthesizing a nucleic acid having a desired sequence and length comprises providing a solid support having an immobilized nucleic acid, performing a nucleic acid addition reaction to elongate the immobilized nucleic acid by adding a nucleotide or an oligonucleotide attached to a protecting group to the nucleic acid, determining whether the nucleotide or the oligonucleotide is added to the nucleic acid, removing the protecting group, and continuing until the immobilized nucleic acid has a desired sequence and length.
