Figure 3From: Probing of Actinobacillus pleuropneumoniae ApxIIIA toxin-dependent cytotoxicity towards mammalian peripheral blood mononucleated cellsDose-dependent cytotoxicity of rApxIIIA on porcine PBMCs. The fraction of PI-positive cells was measured one hour after exposition to serial dilutions of the crude toxin preparation. Values are means ± SDs from three representative experiments. C-, mock-exposed (RPMI-1640) porcine PBMCs incubated for one hour (negative control); C+, paraformaldehyde-exposed PBMCs (positive control).Back to article page
