  • Patent number: 10858695
    Abstract: In some embodiments, provided are methods for nucleic acid amplification include subjecting the nucleic acid to be amplified to partially denaturing conditions. In some embodiments, methods for nucleic acid amplification include amplifying without fully denaturing the nucleic acid that is amplified. In some embodiments, the methods for nucleic acid amplification employ an enzyme that catalyzes homologous recombination and a polymerase. In some embodiments, methods for nucleic acid amplification can be conducted in a single reaction vessel. In some embodiments, methods for nucleic acid amplification can be conducted in a single continuous liquid phase of a reaction mixture, without need for compartmentalization of the reaction mixture or immobilization of reaction components. In some embodiments, methods for nucleic acid amplification comprise a amplifying at least one polynucleotide onto a surface under isothermal amplification conditions, optionally in the presence of a polymer.

  • Publication number: 20200325522
    Abstract: Provided herein are methods for detection and characterization of a target nucleic acid from a single cell. Some embodiments highlight the capability of identifying the biologically relevant variants at the moment of the diagnosis, but also how the treatment positively select resistant cellular clones based on the mutation signature. This positions the Tapestri™ platform described herein as the only tool available to study how genetic variants co-exist and which combinations are sensitive and resistant to certain treatments.

  • Publication number: 20200232011
    Abstract: Provided herein are methods for detection of a target nucleic acid from a single cell. Preferred embodiments of the method include selecting one or more target nucleic acid sequence of interest in an individual cell, where the target nucleic acid sequence is typically complementary to cellular DNA, including a genomic DNA, and an RNA in a cell. A cell sample is provided, and in preferred embodiments the sample is from a single cell. The cell is lysed and in a single reaction both DNA and RNA can be detected without sub-dividing the sample. This can be accomplished by providing nucleic acid amplification primer sets complementary to one or more target nucleic acid, and in particular primer sets that selectively amplify particular target nucleic acids or amplicons in an amplification reaction. Also provided are methods of primer design for these methods and apparatus and system used to perform the methods.

  • Patent number: 10526601
    Abstract: In certain embodiments, the present invention provides a way of “digitally” marking different the alleles of different chromosomes by using a transposase to insert differently barcoded transposons into genomic DNA before further analysis. According to this method, each allele becomes marked with a unique pattern of transposon barcodes. Because each unique pattern of transposon barcodes identifies a particular allele, the method facilitates determinations of ploidy and copy number variation, improves the ability to discriminate among homozygotes, heterozygotes, and patterns arising from sequencing errors, and allows loci separated by uninformative stretches of DNA to be identified as linked loci, thereby facilitating haplotype determinations. Also provided is a novel artificial transposon end that includes a barcode sequence in two or more positions that are not essential for transposition.
