Assay Method Information

Assay Name:  Esterase Activity Assay
Description:  Carbonic anhydrase activity was assayed by following the change in absorbance at 348 nm of 4-nitrophenylacetate (NPA) to 4-nitrophenylate ion over a period of 3 min at 25°C using a spectrophotometer (CHEBIOS UV-VIS) according to the method described by Verpoorte et al. [Verpoorte et al., J. Biol. Chem., 242:4221-4229].The inhibitory effects of compounds 1-14 and AZA were examined. All compounds were tested in triplicate at each concentration used.
