Fig. 5From: Generation and immunogenicity assessment of ELPylated virus-like particles of porcine circovirus type 2Comparison of cytokine responses after immunization with two different forms of VLPs. Three mice from each group were sacrificed at 28 dpi for splenocyte isolation. After 72-h stimulation with VLP or Con A, the splenocyte culture media were assayed for three cytokines using commercial ELISA kits. ** indicates p < 0.01 as compared with the control groupBack to article page
