How does bisulfite sequencing work

WebJan 18, 2013 · 4. Use semi-nested PCR on converted DNA. PCR of bisulfite-converted DNA is less efficient than regular PCR. Hence, you will most likely need two rounds of PCR to obtain enough PCR product. Taking a semi-nested approach is a good idea. I use 4 ul of product from the first PCR reaction as template for the second (semi-nested) rePCR. WebBisulfite conversion involves the deamination of unmodified cytosines to uracil, leaving the modified bases 5-mC and 5-hmC. This procedure can then be followed either by PCR amplification or massively parallel sequencing …
