Bromocresol Green is a biological stain used in microbial culture media as pH indicator. Moreover, DNA tracking in agarose gel electrophoresis uses this color. Bromocresol green binds to proteins, so, it can be used for detecting proteins with an optical sensor.
Bromocresol green can reversibly react with hydrochloride acid in a pH dependent manner. Note that if Bromocresol Green binds to serum proteins, a decrease in fluorescent intensity will happen.
