Measurement of NADPH oxidase activity by monitoring the rates of OCR. (A) Comparison of nondifferentiated and differentiated HL60 cells in their response to PMA stimulation. (B) Effect of mitochondrial inhibitors (1 μM rotenone, ROT, and 1 μM antimycin A, ANT) on basal and PMA-stimulated oxygen consumption by dHL60 cells. (C,D) Effect of diphenyleneiodonium (DPI, 10 μM) on basal (ΔOCRBasal) and PMA-stimulated (ΔOCRPMA) oxygen consumption by dHL60 cells.
