Abstract excerpt
The DNA of many eukaryotes is methylated at specific cytosine residues in connection with gene regulation. Here we report a method for the quantification of global cytosine methylation based on enzymatic hydrolysis of DNA, dephosphorylation, and subsequent high-performance cation exchange chromatography. Nucleosides are separated in less than 3 min under isocratic conditions on a benzenesulfonic acid-modified...
