In BEVS for recombinant protein production in insect cells, the promoters of very-late genes, polyhedrin (polh) and p10, coding a major component of the occlusion body (polyhedra) and polyhedra envelope of NPV, respectively, are often used because of their strong promoter activity induced at the very-late phase of infection (~60 h post-infection (hpi)) [17,18]. This evidence concerns the gene POLH and infection.
