Figure 7. Baicalein inhibits IL-1β-induced nuclear translocation of phospho p65 as revealed by immunofluorescence microscopy.

Chondrocyte cultures either served as controls or were treated with IL-1β alone for 30 min or co-treated with 10 ng/ml IL-1β and 50 μM baicalein for 2 h after treatment with IL-1β alone for 30 min. Confocal immunofluorescent analysis of chondrocytes using Phospho-NF-κB p65 Antibody (green), Phalloidin (red) and DAPI (blue).
