Figure 2.
Flow cytometry analysis for oxidative stress. (A–B) Forward scatter histograms. (C–D) 4-HNE staining histograms. H520 cells (A and C) and A431 cells (B and D) treated with 4-HNE antibody labeled dye were examined by flow cytometry (black line: untreated, red line: NIR PIT-treated). A and B indicate expanded cell size only in NIR PIT-treated A431 cells. C and D indicate that oxidative stress marker 4-HNE is stained only in NIR PIT-treated A431 cells.
