Fig. 3.
Correlation between susceptibility to H2O2 toxicity and the level of expression of Bcl-2 protein. The data are compiled from Figs 1 and 2. LD50 is defined as the concentration of H2O2 that kills 50% of the cells after 24 hours of incubation. The level of Bcl-2 protein expression was unaffected by H2O2 treatment (not shown).
