Fig. 2. Garlic extracts function as a NO inhibitor. (A and B) LPS-induced NO production and iNOS expression suppressed by L-NAME NO inhibitor. RAW 264.7 cells were
exposed to LPS (1 lg/mL) and/or L-NAME (100, 300, 500, and 1000 lM) for 24 h. Cells were pretreated for 2 h with the indicated concentration of L-NAME before being
stimulated with LPS. Equal amounts (30 lg) of total protein were loaded in each lane.
