The key of this technical development lies in the houseflies that have been raised at the TARI for 50 years. Houseflies of the strain are extremely sensitive in terms of their neurological immunity. After that, AChE is extracted from inside the houseflies to be the screening reagent for the two major types of pesticides, organophosphate and carbamate.
The reaction with enzyme (AChE) and highly acute toxic substances is a quick biochemistry test method that helps make up for inconvenience of chemical test methods and fulfills the goal of quick screening.
After nearly 20 years of research by agricultural administrative units in Taiwan and the actual application of this technique in agriculture, it was found that serious deviation would result if quality of the enzyme inside living organisms (AChE) is determined simply by activity. The sensitivity of the enzyme (AChE) should be used as an important criterion in the detection of poisons.
