| Derivation |
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.

| Comments |
This cell line exhibits 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.

| 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 or replacement of medium. When replacing media, centrifuge cells and resuspend cell pellet in fresh medium at 1- 2 x 105 viable cells/mL. Maintain cultures at cell concentrations between 1 x 105 and 2 x 106 viable cells/mL. Medium Renewal: 2 to 3 times a week. |
