Insect Cells
Expression Systems offers insect cell lines adapted to serum-free suspension culture in either ESF 921 or ESF AF. The availability of pre-adapted cells saves significant time and expense associated with the adaptation of cultures.
Sf9 Insect Cells
The Sf9 insect cell line is a clonal isolate derived from the parental Spodoptera frugiperda cell line IPLB-Sf-21-AE. Sf9 cells are adapted for suspension culture in ESF 921 or ESF AF and are available as a frozen vial or suspension culture. Sf9 cells are commonly used to produce recombinant baculoviral stocks and to produce recombinant proteins.
Sf21 Insect Cells
The Sf21 insect cell line (IPLB-Sf-21-AE) is derived from ovarian cells of Spodoptera frugiperda. Sf21 cells are adapted for suspension culture in ESF 921 are available as a frozen vial or suspension culture.
Tni Insect Cells
The Tni insect cell line is derived from ovarian cells isolated from Trichoplusia ni. Tni cells are adapted for suspension culture in ESF 921 or ESF AF and are available as a frozen vial or suspension culture.
S2 Insect Cells
The S2 insect cell line is derived from a primary culture of late stage (20-24 hours old) Drosophila melanogaster embryos. S2 cells are adapted for suspension culture in ESF 921 and are available as a frozen vial.
