摘要
目的:建立水痘-带状疱疹病毒(VZV)抗原的双抗体夹心ELISA定量检测方法,用于质控VZV灭活疫苗研发和生产中抗原含量。方法:以VZV中和单抗5F6C8为包被抗体、8H5D1为酶标抗体,构建定量检测VZV抗原的双抗体夹心ELISA方法,并对本方法的特异性、灵敏度、准确性、线性和稳定性等性能进行分析。结果:建立的双抗体夹心定量检测VZV抗原的ELISA方法,线性范围为0.4μg～13μg/ml,相关系数为R2=0.994,定量限度为0.4μg/ml;变异系数CV<15%、准确性回收率介于87.5%～111.6%之间,稳定性37℃6天的回收率>80%。与VZV以外的相关病毒样本没有交叉反应。结论:构建的VZV抗原ELISA定量检测方法的各项性能符合定量检测需要,可用于VZV灭活疫苗的研发和生产过程的抗原含量检测。
Objective：To develop a quantitative enzyme linked immunosorbent assay（Q-ELISA） to determine the concentration of Varicella Zoster Virus（VZV） antigen.This method was used to determine VZV antigen content at each stage of VZV inactived vaccine developing and manufacturing process.Methods： A double antibody sandwich Q-ELISA was developed to determine concentration of VZV antigen,which was based on the the high-affinity neutralizing monoclonal antibodies 5F6C8 as capture antibodies,and 8H5D1 as HRP-labeled antibody.The performance of reagent were evaluated.Results： The Q-ELISA for VZV antigen content was successfully developed.The reagent had good performance.The quantitation scope was 0.4 μg^13 μg/ml,The coefficient correlation was 0.994,the limit of detection was 0.4 μg /ml,the recovery was between 87.5% and 111.6%.The stability was up to 80% after reagent was heated for 6 days at 37℃.The variation coefficient was lower than 15%,and the reagent was no reaction with other sample except VZV antigen.Conclusion： The Q-ELISA for VZV antigen was developed with good specificity,accuracy and stability.The method can be used to determine VZV antigen content during development and production of VZV inactived vaccine.
