Bromophenol Blue is a pH indicator and a dye appearing as a strong blue color. It is often used as a tracking dye during agarose or polyacrylamide gel electrophoresis. Bromophenol blue has a slight negative charge and will migrate the same direction as DNA allowing the user to monitor the progress of molecules moving through the gel. The rate of migration varies with gel composition.
