摘要:

采用胶体金为标记物制备了快速定量检测Asia 1型口蹄疫病毒(FMDV)免疫层析试纸条,拟合检测曲线,用金标分析仪进行定量检测。应用实验室与田间的样品检测证实其有较好的敏感性和特异性。对Asia 1型FMDV抗原定量检测可以在15 min内完成,灵敏度为0.78 μg•mL-1,线性范围在0.78~7.84 μg•mL-1;变异系数在0.2%~5%;回收率在91%~102%,证明定量检测、准确度高。结果表明,本研究建立的定量检测Asia 1型口蹄疫病毒的胶体金免疫层析方法能简便、廉价、快速、灵敏、特异、准确地定量检测样品中的Asia 1型口蹄疫病毒。

Abstract:

The study was conducted to develop a rapid and quantitative colloid gold immuno-chromatography assay of Asia 1 type Foot-and-Mouth disease (FMD) virus.Aiming at detecting FMD virus of Asia 1 type quantitatively,the colloid gold-based immuno-chromatographic test strip was prepared and the standard curve was constructed.Testing the laboratory samples and field samples,results showed that this assay had good sensitivity and specificity.This method could accomplish qualitative and semi-quantitative detection in 15 minutes; the sensitivity was up to 0.78 μg•mL-1 with a linear ranging from 0.78 to 7.84 μg•mL-1.The coefficient of variation was 0.2% to 5%,and the recovery reported to be 91% to 102%.Good reproducibility and accuracy of this method was demonstrated.The colloidal gold immuno-chromatographic assay is rapid,specific,sensitive,accurate,worthy to recommend its clinical use.
