Figure 2: Cell viability measured by CCK-8 assays. Hippocampus neurons were grown on 96-well plates. Aβ alone or incubated with different concentrations of KSE (7.5, or 50μL)at 37°C, was added to hippocampus neurons for 48 h and cell viability was measured using the CCK-8 assay at 1 h. Data represents the percentage of viable cells relative to untreated cells.Values are the mean ± SD of three measurements. **p<0.01, *p<0.05 compared with the controls.
