520 |a Viral envelope proteins play important roles in viral infection and assembly. The grouper iridovirus ORF 64L (GIV-64L) was predicted to encode an envelope protein and was conserved in all sequenced Ranaviruses. In this study, the complete nucleotide sequence of the GIV-64L gene (1215 bp) was cloned into the isopropyl β-D-1-thiogalactopyranoside (IPTG) induction prokaryotic expression vector pET23a. The approximately 50.2 kDa recombinant GIV-64L-His protein was induced, purified and used as an immunogen to immunize BALB/c mice. Three monoclonal antibodies (mAbs), all IgG1 class antibodies against GIV-64L protein, were produced by enzyme-linked immunosorbent assay. Reverse transcription polymerase chain reaction analyses revealed GIV-64L to be a late gene when expressed in grouper kidney cells during GIV infection with cycloheximide (an inhibitor of protein synthesis) or cytosine arabinoside (an inhibitor of DNA synthesis) present. Finally, one of the established mAbs, GIV-64L-mAb-17, was used in Western blotting and an immunofluorescence assay, which showed that GIV-64L protein was expressed at 24 h post-infection and localized only in the cytoplasm in GIV-infected cells, packed into a whole virus particle. The presently characterized GIV-64L mAbs should have widespread applications in GIV immunodiagnostics and other research, and these results should offer important insights into the pathogenesis of GIV
