Fig. 3From: Screening and evaluation of the strong endogenous promoters in Pichia pastorisThe properties of P0208 and P0627. A The relative transcriptional level of P0208-lacZ or P0627-lacZ after 12–60 h growth in YPD broth. The ACT1 gene was used as the reference gene. B The growth curve and β-galactosidase activity of GS115/P0208-lacZ-TADH1 or GS115/P0627-lacZ-TADH1 strain cultured in YPD broth. Error bars indicate the SD for samples tested in triplicateBack to article page
