摘要: 本研究使用盐酸克伦特罗荧光定量检测试剂盒,基于免疫荧光层析原理,实现对猪尿中所含克伦特罗的定量检测,并对试纸条的灵敏度、准确度与精密度、特异性、稳定性等进行了初步的性能评价。结果表明,以四参数法对定量曲线进行拟合,线性系数为R2=0.99972;检测限达到0.1 μg/L;对3个不同浓度的添加回收试验,测得其回收率为80%~120%;批内变异系数分别为12.2%、11.1%、15.2%;与4种β-肾上腺素受体激动剂和8种常用的抗生素交叉反应率均低于0.01%;同时验证了本试剂盒在1年的保存期限有效。整个检测过程只需15 min。

Abstract: Quantitative detection of the clenbuterol in pig urine was investigated with a clenbuterol kit based on immunofluorescence chromatography and a fluorescence quantitative detector,and the sensitivity,accuracy,precision,specificity,stability of the strip were evaluated.The results showed that the quantitative curve fitting was performed by using four parameters method,the linear coefficient R2 was 0.99972.The detecting limit was up to 0.1 μg/L.The recovery rate of 3 different concentration levels were 80% to 120%.The intra assay coefficient of variation were 12.2%,11.1% and 15.2%,respectively.The cross reaction with the 4 β-agonists and 8 antibiotics was less than 0.01%.The experiment confirmed that the kit had 1 year shelf-life.The total detection process just needed 15 min.

Key words: clenbuterol; fluorescent quantitative immunochromatographic method; detection
