Expression of VP1 protein in BHK cells.

<p>Primary rabbit anti-FMDV type O-IgG antibody (LVRI) was applied to the cells, which were then incubated with FITC-conjugated goat anti-rabbit-IgG (Sigma). (A) BHK cells transfected with the eukaryotic plasmid pRC/CMV-VP1 show typical cytoplasm immunospecific fluorescence. (B) BHK cells transfected with pRc/CMV alone express no immunofluorescence.</p>
