title: [Development a method of quantitative assay for enterovirus 71].
abstract: OBJECTIVE
  To establish a quantitative assay for enterovirus 71, this can be used in detecting the virus content during vaccine development and production.
  
  
  METHODS
  We established the method of quantitative assay for EV71 by using double antibody sandwich ELISA. The sensitivity, accuracy,precision and specificity of the method were evaluated.
  
  
  RESULTS
  We developed an ELISA method to quantitative assay for EV71. The quantitation limit of the method is 0.23 microg/ml and the quantitation scope of the method is 7.32-0.23 microg/ml, the coefficient correlation is R2 = 0.9976; The method showed good accuracy, precision and specificity. The recovery is between 90%-110% and the variation coefficient is lower than 10%.
  
  
  CONCLUSIONS
  An ELISA method was developed for the quantitative assay of EV71 virus, which can be used for the rapid quantitative determination of EV71 virus during vaccine development and production.
