A comparison of enhanced green fluorescent protein expression induced by immediate-early cytomegalovirus (IE-CMV) and gG pseudorabies virus (gG-PRV) promoters, using pseudorabies virus amplicons as vectors

This study compares the expression efficiencies of the IE-CMV and gG-PRV promoters following their transfection into cultured human and monkey cells, using pseudorabies virus amplicons as vectors and enhanced green fluorescence protein (EGFP) as an expression marker. EGFP expression was similarly strong with both promoters. Pseudorabies virus amplicons appear to be useful vectors in gene expression studies due to their replication in the presence of helpers and their wide range of cellular hosts.
