Figure 1. Serotonin (5-HT) concentrations in rat tissues.
Enzyme-linked immunosorbent assays (ELISAs) were used to detect 5-HT concentration in rat tissues. The 5-HT concentrations were measured in 100 μg of total proteins extracted from the brain (A), liver (B) and kidney (C) of the rats. *P<0.05 vs healthy group. N=6.
