Fig. 5. Flow cytometric analysis of apoptotic Hy-HUVEC cells induced by NC8-pSIP409-alr-ACEIP. Hy-HUVEC cells were treated with NC8-pSIP409-alr-ACEIP (a) or NC8-alr (b), which was added at bacterium/cell ratios of 20:1, 40:1, 80:1, 160:1, and 320:1 for 2 h. FITC: fluorescein isothiocyanate; PI: propidium iodide; ACEIP: angiotensin-converting enzyme inhibitory peptide.
