Bromocresol green is a dye that is used in biological assays to measure the kinetics of fluorescence. It is a type of tryptophan-releasing compound that releases a yellowish-green light when it absorbs light at wavelengths between 350 and 450 nm. Bromocresol green has been quantified by measuring the intensity of the fluorescence emission as a function of time. This can be done visually or using an instrument called a fluorometer, which detects changes in light intensity over time. Bromocresol green can be used to detect the presence of amino acid residues in proteins through protonation reactions with their tryptophan residues and subsequent quenching with acetonitrile. The bromocresol green dye is also used in lithographic printing, where it serves as an acceptor for electrons from an arene (aromatic hydrocarbon). This process generates energy for lithography and also provides contrast between regions with different electron densities.
