Baculovirus-Insect Cell Protein Expression
Baculovirus-insect cell expression system is widely used to express various recombinant proteins, due to its advantages of high expression level of foreign genes, easy expression of heteromultimeric proteins, and safety. Recombinant proteins expressed by insect cells usually have correct post-translational modifications and biological activities. Insect cells can be cultured in suspension, easy to scale up and culture, which is conducive to large-scale expression of recombinant proteins. The insect cell/baculovirus expression system is very suitable for expression of recombinant proteins located in the cell and nucleus. For toxic proteins and glycoproteins, they can be secreted into the medium by adding secretion signal peptides, such as HBM. LifeSct has established the insect cell expression platform to provide high-quality and affordable eukaryotic protein expression services.
