Figure 1: Comparison of recombinant protein expression levels between BmNPV and AcNPV- silkworm expression system. Recombinant proteins accumulated in supernatants (S) and precipitates (P) of the homogenates of larvae were detected by western blotting using HisProbe-HRP Antibody (Pierce). Larvae (day 2 of the 5th instar) of the d17 strain was infected with BmNPV or AcNPV at the amount of 2 × 104 pfu per larva.
