chlorinated phenols, such as 2,3,4,6-tetrachlorophenol (2,3,4,6-TtCP, 21%), 2,4,5-TCP (12%) and 2,3,5-TCP (15%); however, brominated phenols (BP) are even more recognized than the corresponding chlorinated analogues (ex. 2,4,6-TBP, 710%; 2,4-DBP, 119%). With the aim of finding an explanation for this behavior, theoretical calculations have been performed for those and other halogenated phenols (2,4,6-triiodophenol
尿液中消除的三氯酚(TCP)可以被视为许多化学物质(氯酚,氯苯氧酸除草剂,丙草胺,林丹,六氯苯等)暴露的潜在生物标志物。高通量筛选方法对于执行有效的监视程序很有必要,该程序可能有助于预防某些职业健康疾病。为此,已开发出一种针对3-(3-羟基-2,4,6-三氯苯基)丙酸(半抗原)的多克隆抗血清,用于2,4,6-三氯苯酚的间接酶联免疫吸附测定(ELISA)。 5)通过混合酸酐(MA)方法共价键合至匙孔血蓝蛋白(KLH)。间接ELISA使用通过结合3-(2-hydroxy-3,使用活性酯(AE)方法将6-二氯苯基)丙酸(半抗原4)转化为牛血清白蛋白(BSA)。发现包被抗原的最佳半抗原密度为3摩尔半抗原/摩尔蛋白质。该测定法显示的检出限为0.245 +/- 0.116 microg L(-1),在96孔微量滴定板上进行约1.5小时。报道的ELISA在较小程度上识别其他氯化酚,例如2,3,4,6-四氯酚(2
