Expression Systems offers insect cell lines adapted to serum-free suspension culture in either ESF 921 or ESF AF.

• Recombinant protein expression from transient expression or stable cell line
• Good growth in adherent or suspension culture
• Quality and performance testing

The S2 insect cell line is derived from a primary culture of late stage (20 to 24 hours old) Drosophila melanogaster embryos. S2 cells are adapted for suspension culture in ESF 921 or ESF AF and are available as a frozen vial or suspension culture.

The availability of pre-adapted cells saves significant time and expense associated with the adaptation of cultures.

Culture suspension shipments immediately, liquid nitrogen (vapor phase) for frozen vials.
