Figure 5From: Comparison of immune response generated against Japanese encephalitis virus envelope protein expressed by DNA vaccines under macrophage associated versus ubiquitous expression promotersVirus neutralization assay. Neutralization assay of sera from mice immunized with different constructs. The highest dilution of mice sera that resulted into more than 50% CPE was considered. As a positive control JEV immune peritoneal fluid was used whereas peritoneal fluid from the non immunized mice was used as a negative control.Back to article page
