Figure 2From: Improved elongation factor-1 alpha-based vectors for stable high-level expression of heterologous proteins in Chinese hamster ovary cellsMap of the p1.2-Hygro plasmid vector and the cloning scheme for p1.2-based plasmids. A. Plasmid map. UFR: upstream flanking region of the EEF1A gene; DFR: downstream flanking region; Pl: polylinker region; SV40 prom and SV40 PA: promoter and polyadenylation signal from the SV40 virus. B. Cloning scheme for p1.2-based plasmids.Back to article page
