Immunogenicity properties of authentic and heterologously synthesized structural protein VP2 of infectious pancreatic necrosis virus.
The sole coat protein VP2 of infectious pancreatic necrosis virus (IPNV) was isolated and purified from intact virions, propagated in CHSE-214 cells. Likewise was the full-length VP2 protein isolated and purified upon cloning and expression of the corresponding complete gene in E. coli. The two purified proteins of different synthetic origins carrying identical primary structures were utilized in
