Preparation of enzyme reagent for identification of pesticide residues

Enzyme reagent recognizing pesticides are crucial in enzyme inhibition method for pesticide detection, this article outlined the main approach in preparation of the enzymes recognizing pesticide.Screening sensitive enzymes from the organism source to prepare the enzymes reagent immediately is efficacious strategy. Cloning the enzyme gene from suitable organism,following by the preparation of recombinant enzyme in express system is another promising approach for preparation of enzyme reagent against pesticide.Especially, a new type of biometric material(abzyme) recognizing the pesticide residues was introduced in the paper. Finally,perspective of the preparation of enzyme(including abzyme) recognizing the pesticide residues were pointed out.
