A colour marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis. Bromophenol blue and orange G can also be used for this purpose.
In 1% agarose gels, Xylene cyanol typically migrates at about the same rate as a 4000 base pair DNA fragment. Xylene cyanol or tracking dye on a 6% polacrylamide gel migrates at the speed of a 140 base pair DNA fragment.
