Screening for functional IRESes in P. pastoris. a Schematic diagram of the plasmid vectors. b Screening on the X-gal plate for functional IRESes in P. pastoris. Three different colonies were shown for each IRES. c Quantitative detection of β-galactosidase activity for seven functional IRESes in P. pastoris. The strains transformed with empty vector were used as negative control (NC)
