Xylene cyanol



Xylene cyanol (XC) is most commonly used as an agarose gel electrophoresis size marker. It runs alongside different DNA length markers depending on the % of the agarose gel. Despite its smaller molecular weight of 539g/mol it runs slower than bromophenol blue (670g/mol) because of its charge (1 net negative charge).
