Figure 5

AFA extracts protect A549 cells from oxidative insult. (a) Fluorescence intensity of A549 cells alone (Ctrl) or treated with H2O2 or AFA-sE or AFA-sHS alone or cotreated with H2O2 and AFA-sE or AFA-sHS measured by the DCFH-DA assay. (b) Fluorescence microscopy images of untreated cells (Ctrl) and cells treated with H2O2 or cotreated with H2O2 and the AFA extracts.
