H2O2-induced cell apoptosis assay
by flow
cytometry, utilizing Annexin V vs propidium iodide (PI) staining.
Cells in region R3 represent living cells (Annexin V-negative, PI-negative).
Cells in region R2 represent late apoptotic cells (Annexin V-positive,
PI-positive). Cells in region R1 represent early apoptotic cells (Annexin
V-positive, PI-negative). Cells in region R4 represent damaged membranes
only: (A) H2O2 (150 μM), (B) mini-αA
(20 μg/mL) with H2O2, and (C) CP1 (20
μg/mL) with H2O2. (D) Average of three
independent experiments.
