摘要: 用辣根过氧化物酶通过戊二醛法标记甲肝病毒单克隆抗体,建立了甲肝病毒双抗体夹心ELISA(DAS-ELISA)检测方法。在ELISA反应中酶标抗体的工作浓度为1:100稀释,对甲肝病毒的检测灵敏度为2μg/ml。在草莓汁液中添加灭活的甲肝病毒,该ELISA的检测下限被推荐为4μg/ml。甲肝病毒ELISA方法便捷、可靠,适用于草莓上携带甲肝病毒的检测。

Abstract: Monoclonal antibody against hepatitis A virsus (HAV) was labeled with horseradish peroxides (HRP) in glutaraldehyde,and a double-antibody sandwich ELISA (DAS-ELISA)method for detection of the HAV was developed. The optimal working concentration for HRP-antibody at a dilution of 1:100 is determined,and the lowest detection amount of the HAV dissolved in PBS is determined as 2μg/ml. When adding the inactivated HAV to strawberry juice,the detection limit of the antigen is 4μg/ml by ELISA. The ELISA is convenient,reliable and suitable method for detection of HAV in strawberries.
