aromatic ring and metal carbonyl complex) was used for further study by CMIA. Reproducible competitive standard curves were obtained by using anti-simazine antibodies in PBS buffer pH 7.4 with pre-incubation of various amounts of atrazine and antibodies for 1 h at 4 °C before addition of the tracer. This study demonstrates the feasability of using CMIA for pesticide determination, although the sensitivity
对非同位素免疫测定法(CMIA)进行了定量除草剂阿特拉津的研究。该测定法结合了过渡金属羰基配合物和傅里叶变换红外光谱。我们描述了三种二钴六羰基示踪剂,,去津的衍生物的合成。通过ELISA和CMIA评估了它们对多克隆兔抗血清的两个纯化的IgG级分(抗阿特拉津和-辛嗪)的相对结合亲和力。最好的示踪剂9(在IA去津芳族环和羰基金属络合物之间具有最长的烷基链)被CMIA用于进一步研究。通过在PBS缓冲液pH 7.4中使用抗Simazine抗体并在添加示踪剂之前在4°C下预孵育各种量的阿特拉津和抗体1 h,可获得可再现的竞争标准曲线。这项研究证明了使用CMIA进行农药测定的可行性,尽管当前CMIA格式的灵敏度未达到欧盟要求的0.1μgl -1水平
