bisulfite Methods, Protocols and Troubleshootings

Bisulfite sequencing (also known as bisulphite sequencing) is the use of bisulfite treatment of DNA before routine sequencing to determine the pattern of methylation. DNA methylation was the first discovered epigenetic mark, and remains the most studied. In animals it predominantly involves the addition of a methyl group to the carbon-5 position of cytosine residues of the dinucleotide CpG, … WebSequencing bisulfite-altered DNA is the most straightforward means of detecting cytosine methylation. In general, after denaturation and bisulfite modification, dsDNA is obtained by primer extension and the fragment of interest is directly amplified by PCR [47] or cloned into a suitable plasmid vector. Direct bisulfite sequencing/PCR has poor ... ray healy
