Fig. 1From: Lycium barbarum polysaccharide protects HSF cells against ultraviolet-induced damage through the activation of Nrf2Relevant characteristics of LBP and Nrf2. a – The optical absorbance of LBP at different optical densities. b – The protein levels Nrf2 in the cytosol and the nucleus. The plotted graph indicates the level of nuclear Nrf2 at different concentrations of LBP. Experiments were repeated at least in triplicates, *p < 0.05Back to article page
