Abstract: 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.

Abstract: It is intended to detect, concentrate and purify aflatoxins of all types which are possibly contained in a sample such as a food. It is also intended to detect the total amount or the individual amounts thereof at a high sensitivity. By using aflatoxin B2 or its derivative as a hapten compound, an antibody, which shows the same reactivity to individual aflatoxin analogs and is highly tolerant to organic solvents, is obtained. Then, a detection/concentration/purification means and an immunological detection means with the use of the above antibody are constructed. The detection means thus constructed achieves a high sensitivity and excellent quantification properties.
