Fig 3. Effect of CT302 IgG1 on the membrane fusion and the traffic of viral nucleoprotein to nucleus.

Fig 3

Entry fusion (EF) assay: Virus particles were labeled with DiOC18 and R18, and were allowed to enter CT302 IgG1-, Bafilomycin A1- or control IgG1-treated cells. Fusion of viral and vacuolar membranes of cells triggered dequenching of DiOC18 (green) signal co-localized with the R18 (Red) signal. Nuclear import (EI assay): In the CT302 IgG1-, BafilomycinA1- or control IgG1-treated cells, virus particles were allowed to enter nucleus. Incoming NP proteins (green) were detected within the nucleus (blue) by the anti-NP antibody. Magnification: 20×.
