Tag: <span>protein overexpression</span>

The baculovirus expression vector system, which is based on infecting insect cells with recombinant Autographa californica nuclear polyhedrosis virus (AcNPV), is one of the most commonly used eukaryotic expression systems aimed at producing functionally active mammalian proteins. It offers advantages such as high-level protein expression and post-translational processing capabilities that are extremely important to the biological activity of certain proteins. This system utilizes a strong promoter of the very late gene, polyhedrin, to drive heterologous protein overexpression. Nevertheless, in order to generate milligram amounts of recombinant proteins, cell culture often needs to be scaled up to as much as 25 liters….
