Figure 8From: Construction and characterization of new piggyBac vectors for constitutive or inducible expression of heterologous gene pairs and the identification of a previously unrecognized activator sequence in piggyBacExpression levels induced by precursor plasmids and constitutive piggyBac vectors. The plot shows the levels of enzyme activity induced by precursor plasmids or piggyBac vectors encoding the six heterologous genes of interest under the control of the constitutive transcriptional control element. Black bars show the levels obtained with the precursor plasmids, white bars show the levels obtained with the piggyBac vectors containing heterologous genes in the rightward orientation, and gray bars show the levels obtained with the piggyBac vectors containing heterologous genes in the leftward orientation.Back to article page
