Figure 1From: Cysteine protease activation and apoptosis in Murine norovirus infectionCaspase activation during MNV-1 infection. Mock-infected (top) and infected (bottom) RAW246.7 cells were incubated with a poly caspase specific activity-based probe 2, 4, 8, and 12 hours post infection (left to right). The poly-caspase probe is membrane permeable and linked to a sulforhodamine dye.Back to article page
