Construction of Recombinant Baculoviruses.

ABSTRACT

The success of using the insect cell-baculovirus expression technology (BEST) relies on the efficient construction of recombinant baculovirus with genetic stability and high productivity, ideally within a short time period. Generation of recombinant baculoviruses requires the transfection of insect cells, harvesting of recombinant baculovirus pools, isolation of plaques, and the expansion of baculovirus stocks for their use for recombinant protein production. Moreover, many options exist for selecting the genetic elements to be present in the recombinant baculovirus. This chapter describes the most commonly used homologous recombination systems for the production of recombinant baculoviruses, as well as strategies to maximize generation efficiency and recombinant protein or baculovirus production. The key steps for generating baculovirus stocks and troubleshooting strategies are described.
