Phenolphthalein β-D-Glucuronide (hydrate)

Phenolphthalein β-D-glucuronide is a colorimetric substrate for β-glucuronidase.1 Upon enzymatic cleavage by β-glucuronidase, phenolphthalein is released, which can be quantified by colorimetric detection at 552 nm as a measure of β-galactosidase activity.1,2WARNING This product is not for human or veterinary use.
