Figure 5From: Cytotoxicity of purified listeriolysin O on mouse and human leukocytes and leukaemia cellsLLO stability in the presence of protease inhibitors tested on Jurkat cells incubated in RPMI 1640 medium containing 4% inactivated NCS. Presented values show percentage of living cells after exposure to LLO. Median value, P25 and P75, n = 3, p < 0.0001 compared with controls without inhibitors.Back to article page
