Figure 3: In vitro inhibition of NAT activity from rat liver samples by apocynin.

The impact of varying concentrations of apocynin (0 and 10 mM) on the activity of rat liver NAT from S9 fractions (9.60 μg protein) of untreated rat livers was investigated in-vitro, as described in methods. Assays were conducted in triplicate and all values are expressed as mean ± standard deviation values.
