  • Publication number: 20240011020
    Abstract: Disclosed herein are compositions, kits, and methods for amplifying a sequencing assay region of a target nucleic acid from a nucleic acid sample from any source, while simultaneously adding a plurality of barcode sequences during the amplification process, to create a library of amplified amplicons which is then sequenced, with the barcode sequences enabling identification of the nucleic acid sample from which the amplicon derives. The compositions and methods can be used, for example, to create amplicons containing combinatorial barcodes for the purposes of rapidly sequencing many nucleic acid samples for the presence of viral or mutant nucleic acids.

  • Publication number: 20180010120
    Abstract: The present invention features, inter alia, compositions and methods for preparing, from a plurality of original, nucleic acid-containing samples, a unified library of linear, non-selectively amplified DNA fragments in which the proportional representation of the fragments from each of the plurality of original samples is normalized and the library is created in a highly parallelized, pool-based fashion. The invention is particularly useful for preparing libraries in which specific information is encoded that allows shorter sequencing reads derived from high-throughput sequencing of the library to be analyzed or assembled into longer scale sequences that are fully traceable to an original, nucleic acid-containing sample within a potentially very large collection of samples. The compositions of the invention encompass the various constructs described herein, which may be variously packaged with one or more additional reagents useful in the present methods and instructions for use.

  • Patent number: 5512458
    Abstract: Doubled-stranded oligonucleotide molecules for use in providing enchaned sequencing of DNA, comprising: a first stand having 1) a priming site; 2) a labeling region contiguous with the priming site, wherein the labeling region consists essentially of at least six identical nucleotides; and 3) a cohesive end contiguous with the labeling region, having a nucleotide sequence complementary to a nucleotide sequence generated by the action of a restriction enzyme; and a second strand annealed to the labeling region of the first stand, but not overlapping with the cohesive end. A method of DNA gene sequencing, involving the use of mobile priming sites for DNA polymerases in DNA sequencing, is also disclosed.
