A graph illustrating the antigenicity and specificity of the recombinant VP1 as measured in a direct ELISA where the expressed VP1 protein was immobilized, then incubated in octuplicate with sera from guinea pigs that were immunized with FMDV SAT1, 2 and 3 viruses, respectively. Serum of naïve guinea pigs were included as controls (error bars represent the standard deviation)
