Insect Baculovirus Expression System

Insect baculovirus expression is a recombinant protein production system that uses recombinant baculoviruses carrying exogenous target genes as vectors for expression in insects. The recombinant proteins can be fully functional as they undergo post-translational modifications such as glycosylation, phosphorylation, acylation, and signal peptide cleavage. These modifications are similar to those in mammalian cells. By using strong promoters like p10 and pH, it can reach a high expression level, can accommodate large-size insertion fragments, and express multiple genes simultaneously. The Biortus team has over a decade of rich experience in protein expression, and has successfully completed more than 9000 batches of protein expression services in total.
