Fig. 5From: Identification of four insertion sites for foreign genes in a pseudorabies virus vectorConfirmation of S and PRV protein expression by the recombinant PRV using indirect immunofluorescence assay. Pig anti-sera against PEDV or PRV in conjunction with FITC labelled anti-pig secondary antibodies were employed to verify S and PRV protein expression.
