Re: Difference between histone's and DNA's methyltransferase?

... specific PCR (MSP). First you treat DNA with sodium bisulfite under alkaline conditions.Result is conversion of unmethylated Cs to Us.Methylated ... is methylated(so C is not converted to U).If primer anneals and you get reaction then C was methylated..Use it to measure activity of enzyme somehow
