Aerosol infectivity of a Baculovirus to Trichoplusia ni larvae: An alternative larval inoculation strategy for recombinant protein production.

The baculovirus-insect expression system is a popular tool for recombinant protein production. The standard method for infecting insect larvae with recombinant baculovirus for protein production involves either feeding occlusion bodies or injecting budded virus into the cuticle. In this study, we showed that the recombinant Autographa californica multiple nucleopolyhedrovirus (AcMNPV) at titers >10(8) pfu/mL efficiently infected Trichoplusia ni (T.
