Fig. 4From: Generation and immunogenicity assessment of ELPylated virus-like particles of porcine circovirus type 2Comparison of the antibody responses after immunization with two different forms of VLPs. Mice were immunized two times with the same dose of ELP-VLP or VLP without use of adjuvant. a The serum samples were collected from the immunized and control mice at indicated time and analyzed for the Cap-specific IgG antibody. b The serum samples were collected from the immunized and control mice at 28 dpi and analyzed for PCV2 VN antibody. *, ** and *** indicate p < 0.05, p < 0.01 and p < 0.001 as compared with the control groupBack to article page
