FIG 2.

The relative contribution of the cloned and genome encoded coat F genes to coat protein levels during infections. Cells harboring the cloned F gene were infected with (+) and without (−) cloned gene induction at an MOI of 3. The cloned gene was induced at the time of infection (0 min) or 20 min before infection (−20 min). (A) The digitally unadjusted, Coomassie blue-stained, SDS-PAGE gel of whole-cell lysates. The marker lane contained purified virions. (B) The digitally modified gel used for more accurate densitometry measurements using the ImageJ (NIH) program. Coat/external scaffolding protein ratios were determined and are shown.
