Fig. 3From: SjCa8, a calcium-binding protein from Schistosoma japonicum, inhibits cell migration and suppresses nitric oxide release of RAW264.7 macrophagesConfirmation of the effects of rSjCa8 on RAW264.7 cell apoptosis by confocal microscopy. Cells were exposed to Annexin-V-FITC and PI for 30Â min prior to analysis. The fluorescence of apoptotic cells was detected under a confocal microscope (a) and the apoptosis rate was calculated (b). The graph shows the means of three independent experiments that were performed in triplicateBack to article page
