Bisulfite sequencing and its limitations. Bisulfite selectively deaminates various cytosines, which can aid in localizing modifications upon PCR amplification and sequencing. Problematically, sodium bisulfite is both destructive and unable to distinguish between the two most common modifications in mammalian genomes, 5mC and 5hmC.
