The insect cell expression and purification system is a versatile and robust platform used for producing a wide range of proteins. It offers distinct advantages, such as accurate post-translational modifications (PTMs), increased yields for secreted proteins, improved solubility, and the ability to support relatively high cell culture densities. These benefits make insect cell lines an excellent choice for expressing various types of proteins, including intracellular proteins, protein complexes, kinases, membrane proteins, and viral proteins.
At WuXi Biologics, our Protein Sciences (PS) Department provides a range of commonly used insect cell lines, such as Sf9 and HighFive. We leverage optimized expression vectors, host cells, and advanced virus packaging technology to ensure consistent and high levels of protein expression, resulting in the delivery of premium-quality proteins.
