The Methylated cytosine DNA standard kit is a set of five DNA standards that are linear dsDNA, 426 bp, and have the same sequence (see sequence below & figure). The only difference is that each contains either normal cytosines, 5-methylcytosines, 5-hydroxymethylcytosines, 5-formylcytosines, or 5-carboxylcytosines. Since the sequence and extent of cytosine modification is known, this DNA standard set is ideal for use in calibration of various applications intended for quantitation of cytosine modifications.
