Detection of apoptosis in U87 cells treated with 10 µM Aβ1–42 for 48 h using DAPI staining. Cell nuclei were stained in blue. Representative photos for DAPI staining in U87 cells treated with (A) 0 µM and (B) 10 µM Aβ1–42 at ×100 magnification. Scale bar, 100 µm. Representative photos for DAPI staining in U87 cells treated with (C) 0 µM and (D) 10 µM Aβ1–42 at ×200 magnification. Scale bar, 50 µm. Aβ, amyloid β.
