Figure 6From: Immunization of mice by Hollow Mesoporous Silica Nanoparticles as carriers of Porcine Circovirus Type 2 ORF2 ProteinIdentification of specificity of mouse antibodies in PK15 cells infected with PCV2 by immunofluorescent microcopy. (a) PK15 cells were infected with PCV2 at 10-4.3 TCID50 for 72 h, and then incubated with mouse antibody to PCV2 GST-ORF2-E. (b) Non-infected PK15 cells were used as a negative control.Back to article page
