Degradation of DNA by bisulfite treatment

Bioorg Med Chem Lett. 2007 Apr 1;17(7):1912-5. doi: 10.1016/j.bmcl.2007.01.040. Epub 2007 Jan 24.

Abstract

A significant level of target degradation was caused by bisulfite treatment for methylcytosine-selective hydrolysis. The depyrimidination proceeded via addition of bisulfite to pyrimidines in DNA. The quantification with real-time PCR after conventional bisulfite treatment showed a large decrease in the amount of full-length DNA.
