Abstract. A procedure of synthesis of the enzymatic marker 3,6-dichloro-2-methoxybenzoic-alcaline phosphatase is described. This bioconjugate is used as reagent in ELISA technique to monitor this pesticide from environmental samples. According the procedure, 3,6-dichloro-2-methoxybenzoic acid is activated with N-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide in anhydrous medium of dimethylformamide and then coupled to alkaline phosphatase. The enzymatic activity and the evaluation of the affinity against homologue antipesticide antibody are also described.
Key words: immunoassay, dicamba, affinity, antipesticide, antibody.
