    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 540149

CAS#: 149-91-7

Description: Gallic acid is found in varitingous plant sources and used to determine phenol content of analytes. It displays many biological activities, including inducing Fas-mediated apoptosis in breast cancer cells inhibiting the production of α-hemolysin and cell adhesion in Staphylococcus, and increasing levels of antioxidatice enzymes, limiting oxidative damage.
