A uniform quantitative enzyme-linked immunosorbent assay for Coxsackievirus A16 antigen in vaccine.

ABSTRACT: Coxsackievirus A16 (CV-A16), one of major etiological agents of hand, foot and mouth disease (HFMD), causes outbreaks of the disease in young children all over the world. In order to promote the prevention and control of HFMD, the research and development of CV-A16 vaccine have been carried out in China. However, due to lacking of a recognized CV-A16 antigen detection method, the evaluation and quality control (QC) of vaccine effectiveness are greatly limited. In this study, we established a quantitative enzyme-linked immunosorbent assay (Q-ELISA) to determine the antigen concentration in CV-A16 vaccines that can be applied in manufacturing in China. A neutralizing antibody 16E1 was used as a capture antibody that can bind to various CV-A16 antigens of different subgenotypes, and an antise
