Bisulfite Sequencing - detect DNA Methylation - YouTube

Bisulfite sequencing is used widely across mammalian genomes, however complications have arisen with the discovery of a new mammalian DNA modification 5-hydroxymethylcytosine. 5-Hydroxymethylcytosine converts to cytosine-5-methylsulfonate upon bisulfite treatment, which then reads as a C when sequenced. Therefore, bisulfite sequencing cannot discriminate between 5-methylcytosine and 5-hydroxymethylcytosine. This means that the output from bisulfite seque… WebWhat does bisulfite conversion do? Bisulfite Conversion is a process in which genomic DNA is denatured (made single-stranded) and treated with sodium bisulfite, leading to deamination of unmethylated cytosines into uracils, while methylated cytosines (both 5-methylcytosine and 5-hydroxymethylcytosine) remain unchanged. WebIn bisulfite conversion, DNA is first denatured so that it is single stranded. The addition of sodium bisulfite will sulfonate unmethylated cytosines at a low pH, which then undergo spontaneous deamination into sulfonated uracil molecules, and subsequent desulfonation results in uracil molecules [28]. kandy best food places

WebJan 19, 2009 · After bisulfite conversion, two consecutive PCR reactions for amplification of the loci of interest were performed. In this study, 11 loci were preamplified in a multiplexed PCR, and each locus was subsequently reamplified in a separate PCR reaction. Thus, this method enables the analysis of the DNA methylation of several genes in one LMD sample. 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 …
