Xylene cyanol can be used as a color marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis; in 1% agarose gels, it typically migrates at about the same rate as a 4000 base pair DNA fragment. Bromophenol blue and orange G can also be used for this purpose.
Xylene cyanol is also known as xylene cyanole, Acid Blue 147, xylene cyanol FF, C.I. 42135, ,and sometimes as xylene cyanole FF.
