Effect of different intron-containing vectors on the transient expression of reporter genes. (A) Vectors containing different introns were transfected into CHO cells and fluorescence intensity was imaged at 48 h post-transfection. (B) The cells were collected after 7 d suspension culture, and the mean fluorescence intensity (MFI) was measured. (C) The level of SEAP activity from transient expression (after 7 d suspension culture). Error bars indicate the standard deviation of triplicate data (*P < 0.05).
