• 活力定義：在37℃,0.1mol/L pH=8.0磷酸緩沖液條件下，每分鐘分解1umol碘化硫代乙酰膽堿（ATCI）的酶量為一個乙酰膽堿酯酶活力單位。

• 介紹：在一定條件下有機(jī)磷和氨基甲酸酯類對膽堿酶正常功能有抑制作用，其抑制率與農(nóng)藥濃度成正比關(guān)系，正常情況下，酶催化神經(jīng)傳導(dǎo)代謝產(chǎn)物（乙酰膽堿）水解，其水解產(chǎn)物與顯色劑反應(yīng)，產(chǎn)生黃色物質(zhì)，用分光光度計測定吸光度隨時間的變化值，計算出抑制率。通過抑制率可測出產(chǎn)品中是否含有有機(jī)磷和氨基甲酸酯類農(nóng)藥的存在。

• 活力：≥200units/g protein

• 性狀：類白色或褐色粉末。

• 來源：取自于對農(nóng)藥極為敏感的蒼蠅頭部。
