WebTreatment of denatured DNA (i.e., single-stranded DNA) with sodium bisulfite leads to deamination of unmethylated cytosine residues to uracil, leaving 5-mC or 5-hmC intact. The uracils are amplified in subsequent PCR reaction as thymines, whereas 5-mC or 5-hmC residues get amplified as cytosines. Comparison of sequence information between the ... WebJan 26, 2007 · With more than 90% DNA degradation during bisulfite treatment, only relatively few molecules are left for PCR amplification. The number of available molecules is also influenced by the length of the target amplicon. Longer amplicons are less likely to amplify, simply because the likelihood to find a single intact starting template decreases ...
