Chemical compound
Xylene cyanol can be used as an electrophoretic color marker, or tracking dye, to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis. Bromophenol blue and orange G can also be used for this purpose.
Once mixed with the sample, the concentration of xylene cyanol is typically about 0.005% to 0.03%.
