  1. ...quantitative nucleotide resolution of methylation. It converts unmethylated cytosine to uracil by chemical deamination, while methylated DNA remains unconverted (Fig. 1B). After polymerase chain reaction (PCR), the methylated and unmethylated bases are distinguished as cytosine (C) to thymine (T) single...

  2. ...-specific methylation analysis in humans to identification of methyltransferase specificity in complex bacterial communities.The covalent modification of cytosine by a methyl group leads to the formation of 5-methylcytosine (5mC), a key epigenetic modification of genomic DNA that occurs in a large number of organisms...
  3. ...genomic DNA spiked with unmethylated lambda, cytosine methylated XP12, and hydroxymethylated T4gt phage genomic DNAs. Lambda and XP12 control DNAs were used to measure the deamination rates of APOBEC3A on C and 5mC, respectively, and T4gt DNA was used to monitor 5hmC protection by BGT. By using...
  4. ...were produced, which yielded an average depth of 223 per strand for each sample (Supplemental Table S2) with ;90% of genomic cytosines (Cs) being covered by at least two unique reads (Supplemental Table S3). We identified an average of 14.5 million methylated cytosines (mCs) in each sample (see Methods...
  5. ...3 was not mapped in HMEC, we cannot assess this phenomenon directly in these cells. However, to identify potential H3K9me3 domains, we searched for regions depleted of DNA methylation that are simultaneously depleted of H3K27me3. These large domains, putatively similar to the H3K9me3 enriched...
  6. ...mammalian development in primordial germ cells (PGCs), yet the targets and kinetics of this process are poorly characterized. Here we provide a map of cytosine methylation on a large portion of the genome in developing male and female PGCs isolated from mouse embryos. We show that DNA methylation erasure...
  7. ...distinguish methylation states in a semi-quantitative, allele-specific manner at individual CpGs within a defined region. Established protocols that positively identify 5-methylcytosine residues in single strands of genomic DNA exploit the sodium bisulfite-induced deamination of cytosine to uracil. Under...
  8. ...-patch, a multiplexed, targeted method for simultaneous mapping of chromatin accessibility and DNA methylation on single molecules To obtain combinedDNAmethylation and chromatin accessibility data on individual DNA strands or molecules, nuclei are probed with M.CviPI, which methylates cytosine in accessible GC...
  9. ..., and is generally associated with transcriptionally inactive regions. Bisulfite sequencing (BS-seq) uses selective chemical deamination of unmodified cytosines to uracil, leaving 5mC unchanged. The extent of methylation at a given CpG in a sample is detected after amplification, sequencing, aligning reads...
  10. ...bp) have a methylated cytosine (C) at the center, whereas negative samples are nonmethylated, as confirmed by SMRT sequencing. All input DNA sequences are processed into 41 bp fixed-length samples. Sequences <41 bp are symmetrically padded with N's. Longer sequences are segmented into consecutive...
