Figure Lengend Snippet: (A) Fibroblasts (NuFF-1) were infected (MOI= 0.5 TCID50/cell) with TB40/E- mCherry -UL33-3xF (UL33-3xF). Cells were next fixed and permeabilized over a 96 h time course, and UL33 was visualized via its FLAG epitopes (green). mCherry (red) is a marker of infection, and DAPI (blue) was used to visualize host cell nuclei. Images were acquired at 40X magnification. N = 3, representative images shown (B) Cells were infected as in (A) , with an additional, parallel culture treated with PAA post-adsorption, which was collected at 72 hpi. Cells were otherwise collected over a 96 h time course, and whole-cell lysates were immunoblotted for the FLAG epitope tag to detect pUL33-3xF. IE1 is shown as a marker of lytic infection, and actin is shown as a loading control. M, mock-infected cells, harvested at 96 hpi. N = 3, representative blots shown.
