Fig. 2From: Immunization with a fusion protein vaccine candidate generated from truncated peptides of human enterovirus 71 protects mice from lethal enterovirus 71 infectionsImmunohistochemical staining indicating weak cross-reactivity between mice sera immunized with the vaccine candidate containing the fusion protein with adult or fetus human brain tissues. Mouse sera immunized with inactivated virus or P646–755 were used as positive controls, and those immunized with E. coli lysate or P70–159 were used as negative controls. The cross-reactivity sites are denoted with white arrows. Magnification: 400×. The scale bars represented 20 μm in the figureBack to article page
