硝基呋喃代谢物ELISA试剂盒之四呋喃唑酮ELISA试剂盒

呋喃唑酮代谢物（AOZ）ELISA快速检测试剂盒

产品简介

硝基呋喃类 （Nitrofurans）化合物是一类合成的广谱性KJ剂，因价格低廉LX佳，被广泛应用于畜牧、水产养殖中，但由于硝基呋喃类KJ剂及其代谢物在动物源性食品中的残留可以通过食物链传给人类，长期摄入会引起各种疾病，对人体有致癌、致畸胎等副作用。1995年起欧盟禁止硝基呋喃类KJ剂在畜禽及水产动物食品中使用，并严格执行对水产中硝基呋喃的残留检测，2002年美国亦随之制定相应法规。我国农业部2002年第193号公告《食品动物禁用的兽药及其它化合物清单》中将硝基呋喃类列为禁用药。

硝基呋喃类KJ剂常用的包括：呋喃唑酮、呋喃它酮、呋喃西林与呋喃妥因，硝基呋喃类KJ剂在生物体内很快被代谢，代谢物与蛋白质结合后能稳定存留一段时间，所以检测硝基呋喃类残留时通常是检测其代谢物。
