H pylori receptor MHC class II contributes to the dynamic gastric epithelial apoptotic response

Figure 2 The effects of ligating versus crosslinking N87 cell surface MHC class II molecules on caspase 3 activation. Using the apoptosis cytometric bead array kit, beads exposed to the samples were run through a flow cytometer to obtain MFI data. These results were normalized to activated caspase 3 standards to give values expressed as ng/L of activated caspase 3.
