| Derivation | The I 2.1 cell line is a FADD 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  Juo P, et al. Essential requirement for caspase-8/FLICE in the initiation of the Fas-induced apoptotic cascade. Curr. Biol. 8: 1001-1008, 1998. PubMed: 9740801
ICR-191 treated clones were serially diluted in 96-well plates in the presence of Fas Antibody for 3 to 5 weeks. Ref |
| Comments | Unlike the parental line A3 that does express FADD, the I 2.1 cell line does not express FADD protein by immunoblot analysis and is completely resistant to Fas-induced death. Complementation of the I 2.1 cell lines with wild-type FADD restores Fas-mediated apoptosis. Fas activation of caspase-2, caspase-3, caspase-7, and caspase-8 is completely defective in the FADD mutant cell line I 2.1. Ref This cell line can be used to study the role of FADD in apoptotic signaling pathways in the absence of overxpression. |
| 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 15%.
|
| 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 cell density between 2 x 105 and 2 x 106 viable cells/mL.
Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density) |
| Cryopreservation | Complete growth medium supplemented with 5% (v/v) DMSO. Cell culture tested DMSO is available as ATCC Catalog No. 4-X.
