Bromocresol Green is used in a variety of colorimetric detection technologies. It is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations and in charge-transfer complexation processes. In TLC, it is used for visualization of the compounds with functional groups whose pKa is below 5.0. And it is ready-to-use spray and dip reagent for chromatography.
