Tni Pro cells (Fig. 1) were infected with a recombinant baculovirus at an MOI of 1. PBA was added at 1% of the culture volume 18 hours post infection. Sf9 cells (Fig. 2) were infected at an MOI of 0.02. PBA was added at 1% or 5% of the culture volume 36 hours post infection. The recombinant protein was secreted into the culture supernatant and harvested daily. Protein expression levels were determined by protein specific ELISA.
