              Overview of baculovirus expression system in insects:

              Baculovirus expression vector system (BEVS) is a eukaryotic expression system, which can fold and modify proteins after protein translation like mammalian cells. It is suitable to express some proteins that may have negative effects on mammalian host cells, such as kinases and toxic proteins.It is widely used in scientific research and industrial production.

              Our technicians have rich experience in the expression of baculovirus recombinant proteins, especially for long-sequence proteins, active kinases and membrane proteins.Our technicians will optimize the output of baculovirus expression system in insects according to the specific properties of the protein to improve the expression of the protein.

              Advantages of baculovirus expression system in insects:

              1、Compared with other commonly used recombinant protein expression systems, baculovirus expression system has the advantages of high level of foreign gene expression, easy expression of Heteropoly protein, safety and so on. The expressed recombinant protein usually has the correct post-translational modification and biological activity, such as the formation of disulfide bond, phosphorylation, glycosylation and so on.

              2、Insect cells grow in suspension and are easy to be enlarged for large-scale expression of recombinant proteins.

              3、It is easy to express Heteropoly protein, which can be achieved by infecting insect cells with multiple recombinant viruses or by infecting insect cells with a virus containing multiple expression frames.

              4、Safety.Baculoviruses do not infect vertebrates.?
