ANXA5 and systemic lupus erythematosus: Using Annexin V binding as an indicator of phosphatidyl serine surface exposure in early apoptotic cells and PI staining as necrosis indicator (Figure 1), we showed that in SLE patients the percentage of early apoptotic cells was not different in comparison with control groups (20.2% ± 1.4 versus 21.1% ± 1.0).
