WebHere, we developed a simple, rapid, and convenient column-based bisulfite treatment method by improving the several critical steps, which leads to consistent C-to-U conversion rate 99-100 %, >75 % recovery of DNA after bisulfite treatment. In addition, it is commercially viable and requires very less amount (~10 pg) of DNA. WebThe reaction of bisulfite with aldehydes has a classic position in biochemistry since Neuberg demonstrated in 1918 that the products of fermentation by yeast were altered by the addition of sodium sulfite, which caused the production of equal amounts of the bisulfite addition compound of acetaldehyde and of glycerol. This was concomitant with ...
