A Comprehensive Guide to the Commercial Baculovirus Expression Vector Systems for Recombinant Protein Production

The Baculovirus Expression Vector System (BEVS) is a workhorse for recombinant protein expression for over thirty-five years. Ever since it was first used to overexpress the human IFN-β protein, the system has been engineered and modified several times for quick and easy expression and scale-up of the recombinant proteins. Multiple gene assemblies performed on the baculovirus genome using synthetic biology methods lead to optimized overexpression of the multiprotein complexes. Nowadays, several commercially available BEVS platforms offer a variety of customizable features, and often it is confusing which one to choose for a novice user. This short review is intended to be a one-stop guide to the commercially available baculovirus technology for heterologous protein expression in the insect cells, which users can refer to choose from popular and desirable BEVS products or services.
