Our Protein Expression Systems

Baculovirus Expression

The Baculovirus insect cell expression system is widely used for the production of precisely matured, folded and processed recombinant proteins. In contrast to E. coli, insect cells are able to incorporate post-translational modifications. This unique tool usually yields high amounts of the target protein, making it highly cost effective in comparison to other eukaryotic expression systems. They are also particularly well-suited for expressing secreted proteins.

Project Process

For Baculovirus Expression projects, we start with a pilot study for the expression (to test whether it is high or low), followed by purification of the pilot study if needed. The key factor here is to test the expression, as this is the main challenge for the Baculovirus expression system. You will receive a report following this study. No sample will be shipped.

Following this, you can decide the quantity and purity of protein you desire and we will provide you with a quote. The price varies based on the quantity desired and synthesis process.
