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抗菌剂，因价格低廉疗效佳，被广泛应用于畜牧、水产养殖中，但由于硝基呋喃类抗菌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抗菌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。

硝基呋喃类抗菌剂常用的包括：呋喃唑酮、呋喃它酮、呋喃西林与呋喃妥因，硝基呋喃类抗菌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。
