| Disease： | acute T cell leukemia |
| Gender： | male |
| Storage Conditions： | liquid nitrogen vapor phase |
| Derivation： | The A3 subclone was derived from a Jurkat cell line obtained from the laboratory of Gerald Crabtree at Stanford University.
|
| Clinical Data： | male |
| Comments： | The Jurkat cells were treated with Fas Antibody and isolated by limiting dilution to obtain a cell line that had a low spontaneous rate of resistance to Fas-medicated apoptosis.
The resulting wild-type A3 subclone is very sensitive to Fas-mediated apoptosis.
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.
ICR-191 treated clones were serially diluted in 96-well plates in the presence of Fas Antibody for 3 to 5 weeks.
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. |
| 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. Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density). |
| Cryopreservation： | Freeze Medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage Temperature: Liquid nitrogen vapor phase |
