Figure 2From: 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 piggyBacpiggyBac vector constructions (continued). A. PCR amplification of the fluorescent eye color markers. B. Assembly of intermediate plasmids that include the dual constitutive transcriptional control element, fluorescent eye color markers, and appropriate polyadenylation sites.Back to article page
