ABSTRACT
Objective@#To establish a method for detection of chikungunya virus(CHIKV) antigen.@*Methods@#CHIKV virus like particle(VLP), that contains all structural proteins, was prepared by baculovirus expression system. Mice and rabbits were immunized with the VLP to develop antibodies against CHIKV. A double antibody sandwich ELISA was established for detection of CHIKV antigens. The concentrations of the antibodies used and the reaction conditions were optimized. The detection limit and repeatability of the ELISA was evaluated.@*Results@#The sensitivity and specificity was estimated by 10 mimicking CHIKV sera, 90 health person sera, 40 other virus infected sera. It was show that the specificity of DAS-ELISA was 100%, the detection limit was 10 TCID50, the coefficients of variation (CV) within plate was <5%, the CV of different plates was <10%.@*Conclusions@#The double antibody sandwich ELISA established in this study can be used to detect the CHIKV antigen in acute phase serum of patient and provide a method for detection of CHIKV.
