FIGURE 4:

Recombinant β-galactosidase production levels. Tn-NVN and four other insect cell lines were infected with a recombinant baculovirus encoding E. coli β-galactosidase, cell extracts were prepared at various times post-infection, and (a) β-galactosidase activity assays and (b) western blotting analyses were performed on normalized samples. Panel (c) shows quantification of the western blotting results by laser scanning densitometry. The error bars in the graph shown in Panel (a) represent 95% confidence intervals.
