Sf9 cells in Sf-900™ II SFM

Gibco™ Sf9 cells are commonly used to isolate and propagate recombinant baculoviral stocks and to produce recombinant proteins. Gibco™ Sf9 cells are adapted to serum-free suspension culture in Gibco™ Sf-900™ II SFM, which saves significant time and expense associated with the adaptation of cultures. Gibco™ Sf9 cells (frozen in Gibco™ Sf-900™ II SFM) feature:
• Recombinant protein expression from a variety of expression systems
• Good growth in adherent or suspension culture
• Small, regular size that generates even monolayers and plaques
• Documented lineage from a low passage Master Cell Bank
• Quality and performance testing

Recombinant protein expression from a variety of expression systems
High levels of protein expression in Sf9 cells can be obtained using either the BaculoDirect™ Baculovirus Expression System, the Bac-to-Bac™ Baculovirus Expression System, or the InsectDirect™ Expression System.

Small, regular size that generates even monolayers and plaques
Gibco™ Sf9 cells generate a clean, even monolayer and plaques due to their small, round, regular size. Other cells often form more irregular monolayers and plaques.

Documented lineage from a low passage Master Cell Bank
Gibco™ Sf9 cells (in Sf-900™ II SFM) were prepared as serum-free, suspension cultures from Sf9 cells that originated at the USDA Insect Pathology Laboratory. The original Sf9 cells were cloned from the parental IPLBSF-21 (Sf21) cell line that was derived from the pupal ovarian tissue of the fall army worm, Spodoptera frugiperda. The serum-free Master Cell Banks were prepared at passage 34.

Quality and performance testing
Each lot of Gibco™ Sf9 cells is tested for cell growth and viability post-recovery from cryopreservation. In addition, the Master Seed Bank has been tested for contamination of bacteria, yeast, mycoplasma and virus and has been characterized by isozyme and karyotype analysis.
