Comments: CEM/C1 is a camptothecin (CPT) resistant derivative of the human T cell leukemia cell line CCRF-CEM (see ATCC CCL-119).
The cell line was selected and subcloned in 1991 for resistance to CPT.
The cells exhibit cross resistance to both the water soluble (topotecan) and water insoluble (9-amino-CPT and 10,11-methylenedioxy-CPT) analogs of CPT.
CEM/C1 cells are approximately 31 fold less sensitive to CPT than the parental CEM cells.
CEM/C1 cells display atypical multidrug resistance (MDR) and altered topoisomerase I catalytic activity.
Resistance to CPT is stable for up to six months.
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: Medium Renewal: Every 2 to 3 days
Cultures can be maintained by addition or replacement of medium. Establish new cultures at 2 X 10 exp5 viable cells/ml and maintain between 1 X 10 exp5 and 2 X 10 exp6.
Preservation: culture medium 95%; DMSO, 5%
Doubling Time: 26 hrs
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 CCL-119
