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.
