  • Patent number: 11905555
    Abstract: The methods, compositions, and kits of the disclosure provide a novel approach for a whole genome, unbiased DNA analysis method that can be performed on limited amounts of DNA. can be used to analyze DNA to determine its modification status. Aspects of the disclosure relate to a method for amplifying bisulfite-treated deoxyribonucleic acid (DNA) molecules comprising: (a) ligating an adaptor to the DNA molecules, wherein the adaptor comprises a RNA polymerase promoter comprising bisulfite-protected cytosines; (b) treating the ligated DNA molecules with bisulfite; (c) hybridizing the bisulfite-treated DNA molecules with a primer; (d) extending the hybridized primer to make double stranded DNA; and (e) in vitro transcribing the double-stranded DNA to make RNA.
    Type: Grant
    Filed: November 21, 2022
    Date of Patent: February 20, 2024
    Assignee: The University of Chicago
