pesticides, the cyclodiene group, has been developed. With this aim, several hapten-protein conjugates, characterized by exposure of the common hexachlorinated bicyclic (norbornene) moiety and differing in the linking structure to the carrier protein, were prepared. From mice immunized with these conjugates, several MAbs with the ability to sensitively bind the majority of cyclodienes were obtained.
由于有机氯农药尚未解决的健康影响和对生物的持久性,仍然引起公共卫生关注,这要求对其进行监测需要适当的分析技术。在这项研究中,已经开发了一种基于单克隆抗体(MAb)的酶联免疫吸附测定法,用于检测重要的一组有机氯农药,即环二烯基。为了这个目的,制备了几种半抗原-蛋白缀合物,其特征在于暴露于共同的六氯化双环(降冰片烯)部分并且与载体蛋白的连接结构不同。从用这些缀合物免疫的小鼠中,获得了具有能够敏感地结合大多数环二烯的能力的几种MAb。其中CCD2。选择对环二烯化合物(硫丹,狄氏剂,异狄氏剂,氯丹,七氯,艾氏剂,毒杀芬:环戊二烯:I(50)值在6-25 nM范围内)的最广泛识别的单克隆抗体进行测定。有趣的是,由于六氯环己烷(林丹)的γ-异构体也被很好地识别(I(50)值为22 nM),因此该MAb对其他多氯代环烷具有一定的立体特异性。该免疫测定法对于快速灵敏地测定环二烯杀虫剂和相关化合物可能是非常
