Ginkgolides do not affect the incorporation of Aβ_1–42 into neurons. The amounts of biotinylated-Aβ_1–42 in cell extracts from untreated neurons (hollow bars) or neurons pre-treated for 3 hours with ginkgolide A (solid bars) or ginkgolide B (striped bars) and subsequently incubated with 200 nM biotinylated-Aβ_1–42 for the time periods shown. Each point represents the mean amount of bound biotinylated-Aβ_1–42 (optical density × 1000) ± SD from 9 observations.
