ExpiSf™ CD Medium (Gibco™)

ExpiSf CD Medium is a GMP-manufactured, chemically defined, yeastolate-free, serum-free, protein-free, animal origin-free medium specifically designed for high-density growth, transfection, and baculovirus infection of suspension-adapted Sf9 (Spodoptera frugiperda) insect cells.

ExpiSf CD Medium:
• Delivers high reproducibility and lot-to-lot reliability
• Enables high-yield protein expression that is three times higher than traditional insect expression platforms
• Supports growth of suspension Sf9 cultures to densities of approximately 2 x 10⁷ cells/mL
• Supports high-density baculovirus infection of suspension Sf9 cells
• Supports growth, transfection, and baculovirus infection of Sf9 cells in culture formats from 24-deep well plates to >2 L in shaker flasks
• Is a ready-to-use formulation, with no supplementation required
• Powder format available to facilitate large-scale applications

ExpiSf CD Medium is a core component of the ExpiSf Expression System. For highest level protein expression, the medium is used in combination with a matched protein expression enhancer, ExpiSf Enhancer, which is supplied as part of the ExpiSf Protein Production Kit. Sf9 and Sf21 cells adapted to other commercially-available serum-free media may be adapted for growth in ExpiSf CD Medium. ExpiSf CD Medium is not recommended for adherent cell cultures.
