Insect Cell Culture
Insect cell culture is a common choice for heterologous protein expression. For large-scale production or basic research, insect cells are able to express large quantities of protein with complex post-translational modifications.
Gibco insect media has been formulated for maximum growth and protein yields. This media, in combination with Gibco pre-adapted cell lines, will provide a convenient system to save you time and effort.

Drosophila S2 Cell Culture
Drosophila S2 cells are used for heterologous protein expression in the Drosophila Expression System (DES). The S2 cell line was derived from a primary culture of late-stage Drosophila melanogaster embryos (Schneider, 1972). This adaptable cell line grows without CO2, at room temperature, as a semi-adherent monolayer or suspension in Schneider's Drosophila Medium.
Basic insect cell culture with Grace’s Medium
Grace's Insect Medium is a classic medium for insect cell culture. It was originally designed for the growth of cells from the Australian Emperor Gum Moth, Antheraea eucalypti. Supplemented Grace’s Insect Medium is used for the growth of Spodoptera frugiperda cells, Sf9 and Sf21. Sf9 and Sf21 cells are routinely used to express recombinant protein using the Baculovirus Expression Vector System (BEVS). We also offer Gibco Unsupplemented Grace’s formulations that can be used during transfection of insect cells, or for protein labeling studies (with methionine).
