Fig. 3From: Danggui Buxue Tang, an ancient Chinese herbal decoction, protects β-amyloid-induced cell death in cultured cortical neuronsDBT inhibits Annexin V and PI rates. Representative images of Annexin V-FITC and PI fluorescence staining were shown for the cell apoptosis after drug treatment for 48 h (Aβ: 20 μM; DBT-L: 12.5 μg/mL; DBT-H: 100 μg/mL). Annexin V was visualized by purple signal, and PI was shown in blue color. Scale bar = 50 μMBack to article page
