Figure 2

The relative intensity of target protein HA mediated by baculovirus with different promoters.
The black bar (ā ) was the relative intensity of HA driven by CMV promoter; the gray bar (
)was the relative intensity of HA driven by ie1 promoter; BV-X-HA refers to the recombinant baculovirus with WPRE regulatory elements driven by CMV and ie1 promters, respectively; BV-X-ITRs-HA refers to the recombinant baculovirus with WPRE and ITRs three regulatory elements drives by CMV and ie1 promters, respectively; BV-X-con-HA refers to the recombinant baculovirus without any regulatory elements driven by CMV and ie1 promters, respectively. **Pā<ā0.01.
