Fig. 2

Effect of different intron-containing vectors on the stable expression of reporter genes. The vectors were transfected into CHO cells and selected with BSD to establish stable cell pools. (A) Fluorescence images intensity of EGFP. (B) The mean fluorescence intensity of the EGFP cell pool. (C) The level of SEAP stable expression at day 12 suspension culture. Error bars indicate the standard deviation of triplicate data (*P < 0.05, **P < 0.01).
