| Derivation | The I 9.2 cell line is a caspase-8 mutant of the wild-type Jurkat cell line A3 (see ATCC CRL-2570). Wild-type A3 cells were made neomycin resistant and treated with three cycles of exposure to the frameshifting mutagen ICR-191 to isolate clones harboring recessive mutations that were resistant to killing by Fas antibody. Ref ICR-191 treated clones were serially diluted in 96-well plates in the presence of Fas Antibody for 3 to 5 weeks. Ref |
| Comments | The I 9.2 cell line is functionally defective for caspase-8 and the I 2.1 cell line is functionally defective for FADD.
The I 9.2 cell line and the I 2.1 cell lines are completely resistant to Fas-induced apoptosis. Ref Complementation of I 9.2 cell line with wild-type caspase-8 restored Fas-mediated apoptosis. Ref The I 9.2 cell line is severely deficient in cell death induced by TNF-alpha and is partially deficient in cell death induced by ultraviolet irradiation, adriamycin and etoposide. Ref

| Complete Growth Medium | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing | Cultures can be maintained by addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension in fresh medium at 3 to 5 x 105 viable cells/mL. Maintain cultures at cell concentrations between 2 x 105 and 2 x 106 viable cells/mL. Do not allow the cell concentration to exceed 2 x 106 cells/mL. |
| Cryopreservation | Complete growth medium supplemented with 5% (v/v) DMSO. Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
