| Comments: | 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. [51527 ] ICR-191 treated clones were serially diluted in 96-well plates in the presence of Fas Antibody for 3 to 5 weeks. [51529 ] Two of these ICR-191 treated clones have been deposited at the ATCC . They are I 9.2 (ATCC CRL-2571 ), a clone with a mutation in the cysteine protease caspase-8/FLICE and I 2.1 (ATCC CRL-2572 ), a clone with a mutation in the adaptor FADD. 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. [51527 ] [51529 ] Complementation of I 9.2 cell line with wild-type caspase-8 restored Fas-mediated apoptosis. [51527 ] 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. [51527 ] This cell line can be used to study the role of caspase-8 in apoptotic signaling pathways in the absence of overexpression. |

| Propagation: | ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. Temperature: 37.0°C |
||
| Subculturing: | Protocol: 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 10(5) viable cells/ml. Maintain cultures at cell concentrations between 2 X 10(5) and 2 X 10(6) viable cells/ml. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density) |
||
| Preservation: | Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO Storage temperature: liquid nitrogen vapor phase |

| Related Products: | Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001 recommended serum:ATCC 30-2020 parental cell line:ATCC CRL-2570 |
