Baicalein blocks LPS-induced MD-2/TLR4 association. RAW264.7 cells were pretreated with baicalein (0, 10, 25, 50 μM) for 2 h and then stimulated with LPS (1 μg/ml) for 24 h. Cell lysates were immunoprecipitated with anti-TLR4 antibody and then subjected to immunoblotting analysis of MD-2 and TLR4. Densitometric analysis of the MD-2/TLR4 ratio in the immunoblots of the immunoprecipitates was carried out. ###p < 0.001 vs. the mock group; **p < 0.01, ***P < 0.001 vs. the LPS group.
