Biological Activity
Phenol red (PR) is the standard pH indicator in various cell and tissue culture media, as it provides a quick check for the health of the culture. Phenol red has also been used in multiple protocols to detect cellular hydrogen peroxide as well as peroxidase activity from human peroxidase enzymes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
