Animals were evaluated for immune response at 2 months post-viral infection, and antibody titers are compared in Figure 3 between groups (22122-X1 and 22122-HI): Anti-GPCMV ELISA (Figure 3A); Anti-glycoprotein complexes (gB, gH/gL, gM/gN and PC) ELISAs (Figure 3B). Here, ART4 is linked to viral infectious disease.
