BROMOCRESOL GREEN A.C.S. REAGENT (C005B-078312)

General description

Bromocresol Green is a synthetic triphenylmethane dye that is anionic in nature. At pH 3.8-5.4, it changes color from yellow to blue-green, and is therefore, commonly used as a pH indicator.

Application

Bromocresol green serves as a pH indicator in biology and medicinal experiments.

• It is used widely as a vital stain to study blood-brain permeability.
• It has been used in the pH-sensitive colorimetric determination of glutamate decarboxylase activity.
• It has also been employed in the evaluation of paper-analytical devices for colorimetric analysis of serum samples.
• It is used as a tracking dye for DNA agarose gel electrophoresis, in protein determinations, and in charge-transfer complexation processes.
• It is used in TLC for the visualization of compounds with functional groups whose pKa is below 5.0.
