Abstract:

An indirect ELISA which can detect EBOV antibody was established using the purified the envelope glycoprotein as coating antigen.We use the HRP labeled antibody as the secondary antibody,the positive and negative horse sera as controls.After the reaction conditions were optimized,we analyzed the specificity,sensitivity of the indirect ELISA using serum of horse which immunized with EBOV virus like particles.For further evaluation of application of the ELISA,the results were compared to the neutralization assay based on pseudo-type EBOV.The indirect ELISA could detect the antibody against EBOV specifically and showed no cross-reaction with the positive sera of West Nile Fever et al.The indirect ELISA also showed high coincidence with the neutralization assay based on pseudo-type EBOV in evaluation of the immune response after immunization.The coefficient of variation of inter-batch and intra-batch duplicative tests was less than 8%.The indirect ELISA was successfully developed.It provides an effective and convenient method to kinetic detection of antibody against EBOV after immunization.
