propyl gallate

Propyl gallate has been used to probe the cyanideinsensitive alternative oxidase pathway of oxygen uptake in seeds of Orobanche aegyptiaca. A study of cultured lens epithelial cells treated with H2O2 has indicated that propyl gallate dismutates superoxide ion in a catalytic manner and thus mimics superoxide dismutase activity. Propyl gallate (1 mM) has been utilized to probe the activity of plastid oxidase from Arabidopsis thaliana as expressed in tobacco. A report has investigated the utility of propyl gallate with a gold cluster/fluorochrome-labeled antibody probe for immunofluorescence microscopy and immunoelectron microscopy.
