Figure 6From: Differential expression of nitric oxide synthases in porcine aortic endothelial cells during LPS-induced apoptosisRepresentative iNOS immunofluorescent staining on pAECs. Green fluorescence indicates positive immunostaining revealed by FITC, red fluorescence indicates nuclear staining with Propidium Iodide (A, D magnification 200X; B, C, E, F magnification 1000X). A-C) iNOS protein localization in standard cultured pAECs; a cytoplasmatic signal is evidenced. D-F) iNOS protein localisation after LPS treatment (15 h); a nuclear signal in the form of bright granules is revealed.Back to article page
