Figure 6From: Construction of polycistronic baculovirus surface display vectors to express the PCV2 Cap(d41) protein and analysis of its immunogenicity in mice and swineSerum neutralization (SN) titers in swine immunized with various immunogens. 2-month-old SPF pigs were immunized at the base of the ear by the intramuscular route with PBS, CE, 4Cap(d41) (80 μg), and commercial vaccines, respectively. Sera samples were collected at 14 and 28 days after primary immunization for virus neutralization tests. Data represent the mean ± SD. A P value less than 0.05 was considered significantBack to article page
