PREPARATION METHOD FOR SAMPLE SOLUTION FOR MEASUREMENT WITH IMMUNOASSAY USING FLUORESCENT LIGHT, CELL FOR MEASUREMENT, MEASUREMENT KIT, AND PREPARATION DEVICE FOR SAMPLE SOLUTION

To provide a preparation method for a sample solution for measuring a measurement target compound contained in a food in accordance with an immunoassay using fluorescent light, a cell for measurement, a measurement kit, and a preparation device for the sample solution.SOLUTION: The present invention relates to a preparation method for a sample solution, including a dialysis step of making a measurement target compound transient to a dialysis fluid by bringing a measurement target compound-containing solution containing the measurement target compound into contact with the dialysis fluid via a dialysis membrane, in which a fraction molecular weight of the dialysis membrane ranges from 2×102 to 2×105, and the quantity of the dialysis fluid is less than the quantity of the measurement target compound-containing solution. Concentrations of mycotoxin, shellfish poisons, animal bleeding agents and agricultural crop raising agents contained in foods are measured.SELECTED DRAWING: Figure 1 【課題】蛍光を用いた免疫分析法で食品に含まれる測定対象化合物を測定するための試料溶液の調製方法、測定用セル、測定キット、および試料溶液の調製装置を提供する。【解決手段】測定対象化合物を含む測定対象化合物含有溶液を透析膜を介して透析液と接触させて前記測定対象化合物を前記透析液に移行させる透析工程を含み、前記透析膜の分画分子量が２×１０２〜２×１０５であり、前記測定対象化合物含有溶液量に対して前記透析液量が少ないことを特徴とする試料溶液の調製方法である。食品に含まれるカビ毒、貝毒、動物飼育用剤、および農作物育成用剤の濃度を測定することができる。【選択図】図１
