InsectGO™ SF AOF SF9/SF21 is a serum-free, animal-free, and ready-to-use insect cell culture medium. The medium is mainly developed for Baculovirus Expression Vector System (BEVS) applications in both monolayer and suspension culture. InsectGO™ SF AOF SF9/SF21 has been optimized the contents of amino acids, carbohydrates, vitamins, lipids, and other biologically active materials to improve its performance in virus production and recombinant protein expression. InsectGO™ SF AOF SF9/SF21 is designed for Spodoptera frugiperda cells (Sf9/Sf21), and also support the cell growth for other Trichoplusia ni cell lines. The medium contains no phenol red.
