Chemically Defined, High-Yield Medium for Sf9 Insect Cell Culture
Gibco™ ExpiSf™ CD Medium is a GMP-manufactured, chemically defined, yeastolate-free, serum-free, and animal origin-free insect cell culture medium optimized for the high-density growth, transfection, and baculovirus infection of suspension-adapted Sf9 cells (Spodoptera frugiperda). As a key component of the ExpiSf™ Expression System, it supports recombinant protein expression at levels significantly higher than traditional insect expression platforms.
Key Features and Benefits
-
High-Yield Protein Expression
Enables 3× higher recombinant protein yield per liter than conventional serum-free insect culture media. -
Supports High Cell Densities
Allows Sf9 cells to reach densities of up to 2 × 10⁷ cells/mL in suspension culture, enhancing productivity. -
Versatile Compatibility
Suitable for culture volumes from 24-deep well plates to >2 L shake flasks without re-optimization. -
Ready-to-Use Liquid Format
Convenient liquid formulation with no supplementation required. Also available in dry AGT™ format for large-scale applications. -
Lot-to-Lot Consistency
Manufactured under ISO 13485 and cGMP (21 CFR 820), ensuring consistent performance and regulatory compliance. -
Animal Origin-Free and Defined
Free from animal-derived components, hydrolysates, or undefined proteins, ensuring reproducibility and downstream compatibility.
Recommended Applications
- High-efficiency baculovirus expression
- Protein production for structural biology and vaccine development
- Recombinant protein and virus-like particle (VLP) production
- Small- to large-scale Sf9 cell-based workflows
- Use with ExpiSf™ Enhancer and ExpiSf™ Protein Production Kit
