Methods for the Epigenetic Analysis of DNA, Particularly Cell-Free DNA
20230235380 · 2023-07-27 ·

Methods are provided for the epigenetic analysis of cell-free DNA using organic boranes to convert oxidized 5-methylcytosine residues in the cell-free DNA to dihydrouracil (DHU) residues. Cell-free DNA is contacted with an organic borane selected to successively bring about reduction, deamination, and decarboxylation of oxidized 5-methylcytosine residues such as 5-carboxylcytosine and 5-formylcytosine, resulting in DHU residues in place thereof. Following amplification, the treated cell-free DNA is sequenced, with the DHU residues read as thymine residues. Reaction mixtures, kits and additional methods are also provided, as are related methods for the epigenetic analysis of DNA, including cell-free DNA.

OLIGONUCLEOTIDE CONJUGATES AND PREPARATION AND APPLICATIONS THEREOF

The present invention relates to oligonucleotide conjugates and preparation and applications thereof. In particular, the present invention relates to an oligonucleotide conjugated to a biomolecule (e.g. an antibody) and/or an agent of interest (e.g. a drug). In certain embodiments, the oligonucleotide of the present invention is a hybridized complex of a single strand oligonucleotide carrying a biomolecule and a complementary strand oligonucleotide bearing an agent of interest where the hybridized nucleotide segment acts as a linker to link the biomolecule and the agent of interest in one molecule.
