改进ELISA快速测定牛奶中阿维菌素的前处理方法,以改进后处理液作为标准品基质绘制标准曲线,IC50浓度值为1.9μg/L,与PBS缓冲液测定值相同;对牛奶中阿维菌素的检出限为2.0μg/L,对牛奶样品的加标回收率范围为75.8%-104.8%,批内、批间变异系数均未超过15.0%;以两种前处理方法对实际样品进行处理后检测,改进后处理方法检测结果更接近仪器方法检测值且与检测值相差不大,因此该试剂盒可满足相关残留检测国家标准,能满足我国市场和进出口食品检测需要。
改進ELISA快速測定牛奶中阿維菌素的前處理方法,以改進後處理液作為標準品基質繪製標準麯線,IC50濃度值為1.9μg/L,與PBS緩遲液測定值相同;對牛奶中阿維菌素的檢齣限為2.0μg/L,對牛奶樣品的加標迴收率範圍為75.8%-104.8%,批內、批間變異繫數均未超過15.0%;以兩種前處理方法對實際樣品進行處理後檢測,改進後處理方法檢測結果更接近儀器方法檢測值且與檢測值相差不大,因此該試劑盒可滿足相關殘留檢測國傢標準,能滿足我國市場和進齣口食品檢測需要。

To improve avermectins pretreatment method in milk sample,post-processing liquid as standard matrix was used to draw standard curve. The result showed IC50 value was 1.9μg/L same as PBS buffer measurements. The limit of detection(LOD)was 2.0μg/L. The average recoveries of milk samples ranged between 75.8%-104.8%. Coefficients of variation(CVs)were not more than 15.0%. Two pretreatment methods were used to test the actual samples and result displayed values of post-processing method was closer to the instrument readings. So the kit can meet the national standard residue detection and can be applied in the market and entry-exit food testing.
