After blocking, membranes were incubated overnight with rabbit polyclonal antibodies against eIF4GI and PABP or monoclonal antibodies against GFP, HIV-1 protease, actin and REF-1. After washing, membranes were incubated with antirabbit or antimouse goat antibodies labelled with horseradish peroxidase for 50 min and then revealed with ECL-Plus
