Fig. 1From: Immunogenicity evaluation of inactivated virus and purified proteins of porcine circovirus type 2 in miceSerum antibody level after different immunizations in mice. Inactivated PCV2 and subunit protein Cap+ORF3 + Rep were used as antigens to raise antiserum, respectively. After each immunization, the antisera were collected as described in the Materials and methods section. ELISA was performed using PCV2 as coating antigen.
