The antibody binds the S1 region of the spike protein of PEDV. The S protein is a type I glycoprotein that plays a crucial role in virus attachment, entry, receptor binding, cell membrane fusion and induction of neutralizing antibodies. The S protein can

The specificity of the original format of the antibody was confirmed by ELISA analysis. Immunofluorescence assay revealed that the scFv stained PEDV-infected Vero E6 cells but did not react with uninfected control cells. The scFv was shown to inhibit PEDV infectivity by the plaque reduction neutralization assay (the virus neutralization titer was 6.25 microg/mL). Results showed the a cocktail of the scF fragment, PZZ 24 and PZZ 35 neutralized viral infection at 3.125 microg/mL. Finally, piglets orally administered with a mixture of scFv fragment, PZZ 24 and PZZ 35 showed no to mild clinical symptoms, significantly less viral shedding, no mortality and no intestinal lesions.
