高灵敏黄曲霉毒素B1免疫层析定量检测法的建立
Development of Quantitative Sensitive Immunochromatographic Assays for Detection of Aflatoxin B1
摘要
Abstract
The aim of this work was to establish a highly sensitive quantitative colloidal gold immunochromatographic assay with a test strip reader for the detection of aflatoxin B1 using colloidal gold as label.When the labeling pH was 6.0,the concentration of antigen on T-line was 1.5 mg/mL,the concentration of antibody labeled on the colloidal gold was 4 μg/mL,and the dosage of gold-labeled antibody was 1.2 μL,the sensitivity of the assay was 5.7 ng/L.The results of accelerated aging experiment indicated that the strips shelf time was more than a year.It was proved that this method can meet the needs of the rapid detection of food when the strip was applied to detect cereals and soybean sauce.关键词
