H2O2 concentration in culture medium generated from D-glucose after 1 h post addition of 0–10 mU/ml glucose oxidase (GOx). GOx was added to the medium of culture well without or with confluent cultures of ARPE-19 cells to illustrate the initial linear accumulation of H2O2 as a function of enzyme concentration. Data are from three independent experiments and are the means ± SD of three culture wells per group in each experiment
