Bromocresol Green is a pH sensitive indicator used in the growth medium for microorganisms and titrations. It is useful in various colorimetric detection studies and as an actively tracking dye for DNA agarose gel electrophoresis. It acts as an inhibitor of prostaglandin E2 transport protein. It is also used in TLC for visualizing compounds containing functional groups having pKa less than 5.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
