Figure 1From: The influence of astragalus polysaccharide and β-elemene on LX-2 cell growth, apoptosis and activation Effects of APS on the viability of LX-2 cells. LX-2 cells were treated with different concentration of APS as indicated for 24 or 48 hours. Viability was determined by MTT assay. **P < 0.01, ***P < 0.001 compared to untreated cells at the same time point.Back to article page
