Effect of BS and HS4 insulator on EGFP expression and the relative transcriptional analysis. a Fluorescence intensity of AcEGFP, AcBSEGFP, AcEGFP-HS4, and AcEGFP-HS4−-infected Sf9 cells 72 h p.i. b Transcription of EGFP mRNA in AcEGFP, AcBSEGFP, and AcEGFP-HS4-infected cells 48 h p.i. Error bars denote standard deviation (n = 3). Asterisks indicate a significant difference between viruses (*p < 0.05; **p < 0.01)
