From: Characterization of an envelope gene VP19 from Singapore grouper iridovirus
SGIV VP19 aggregated into virus assembly sites at the late stage of SGIV infection. Cells were infected with SGIV at MOI of 2, and then the immune fluorescence assay was carried out using antibody against VP19 at the indicated time points. Cell nuclei and viral DNA was stained with DAPI. The arrows showed the green fluorescence signal of VP19 protein, and the dashed circles indicated the virus assembly sites (VAS).
