Development of an Enzyme-Linked Immunosorbent Assay for the Insecticide Imidacloprid
摘要:
Enzyme-linked immunosorbent assays (ELISAs) were developed for imidacloprid, a neonicotinoid insecticide. Haptens were designed in such ways that spacer arms were introduced on either the pyridinyl or the imidazolidinyl ring of imidacloprid. Two sets of polyclonal antibodies were raised from rabbits immunized with two different immunogens and were characterized with an indirect ELISA format. Cross-reactivities and effects of organic solvents on the assays were evaluated. One set of antibodies shows approximately equal cross-reactivities to imidacloprid and its major metabolites with half-maximum inhibition concentrations (I-50) Of 73-88 ppb. Another is specific to imidacloprid with an I-50 of 35 ppb. The assay was initially applied to the analysis of imidacloprid in fortified water, coffee cherry, and bean extracts.

A kit and a method are provided for easily measuring the concentration of an active ingredient of a termite insecticide persisting in soil, particularly on site where a termite insecticide was actually applied. A kit of the present invention comprises 1) an extraction unit for extracting, with an solvent, a termite insecticide active ingredient from an object of measurement and 2) a reaction unit including a reaction container for encapsulating an identifying antigen, a fixing member for immobilizing an antibody against an active ingredient, and a sealing member capable of fitting to the reaction container. The kit optionally includes 3) a detection unit for visually or optically detecting a change depending on the concentrations of the active ingredient in the object of measurement, and 4) a dilution unit for diluting the sample solution to a certain ratio.
