A Method for Fast Assessment of OP/CB Exposure in the Japanese Quail (Coturnix coturnix japonica) Using Combined Esterases Enzyme Activity as Biomarkers

Figure 2

Substrate preference for blood plasma sample (nmol min−1 mL−1) and liver homogenate sample (nmol min−1 g−1) preparations. Carboxylase enzyme activity was measured in the presence of individual substrates (final concentration was 2 mM for PrTChI and PSA while 1 mM for BuTChI and AcTChI) and the maximum rate recorded. All values in the figure are the mean ± SE of fifteen individuals quail and each is assayed in duplicate.
