Fig. 5

Synthetic circuit of Mxr1 enhanced scFv expression. After being cultured in BMGY (1% glycerol), cells were cultured in BMMY and induced with 1% methanol daily. a The relative secreted scFv titre is presented. The error bars represent the standard deviation of three biological replicates. One-way ANOVA and the Tukey test were used to determine significance. *, p < 0.05; ***, p < 0.005. b Intracellular proteins after induction were examined by western blotting using an anti-his antibody. GAPDH was used as the loading control
