Based on the bioinformatics analysis of the gene encoding glycoprotein 5 (GP5) of porcine reproductive and respiratory syndrome virus (PRRSV) isolate HH08, two gene fragments were amplified by polymerase chain reaction (PCR), deleting the signal peptide and transmembrane sequences in GP5 gene. Both gene fragments were designated GP5a and GP5b, respectively. They were ligated with a linker and cloned into prokaryotic expression vector, pET-30a. Expression of the protein of interest was induced by isopropyl β-d-1-thiogalactopyranoside. The purified protein was used as an immunogen to elicit antibody in rabbit. The immunoreactivity of the protein was determined using ELISA and Western blot. Biologically active GP5 and anti-GP5 antibody inhibited cell infection by PRRSV. Moreover, the antibody produced in this study was capable of detecting the cell infection by PRRSV and distinguishing this virus from other viruses.
