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: I 9.2細胞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
