| Applications |
The line may be used to study xenobiotic (and carcinogenic) metabolism in the absence of cytochrome P4501A1 activity, which is known to metabolize cytotoxic and carcinogenic intermediates. The c1 (B6NLxv1c2) cell line lacks cytochrome P4501A1 dependent aryl hydrocarbon hydroylase (AHH) activity due to a single point mutation in CYP1A1 leading to premature termination of the translated protein (Asn-414; 56 kDa to 45 kDa). The c1 (B6NLxv1c2) line was derived from Hepa-1c1c7 (ATCC CRL-2026). |
| Storage Conditions |
liquid nitrogen vapor phase |
| Derivation |
The c1 (B6NLxv1c2) line was derived from Hepa-1c1c7 (ATCC CRL-2026). Hepa-1c1c7 has high CYP1A1-dependent aryl hydrocarbon hydroxylase (AHH) activity. N-methyl-N-nitro-N-nitrosoguanidine (MNNS) mutated colonies were selected for benzo[a]pyrene resistance. The c1 (B6NLxv1c2) cell line lacks cytochrome P4501A1 dependent aryl hydrocarbon hydroylase (AHH) activity due to a single point mutation in CYP1A1 leading to premature termination of the translated protein (Asn-414; 56 kDa to 45 kDa). The line may be used to study xenobiotic (and carcinogenic) metabolism in the absence of cytochrome P4501A1 activity, which is known to metabolize cytotoxic and carcinogenic intermediates. It is also a tool to study the putative natural ligand for the induction of this enzyme. |

| Complete Growth Medium |
Alpha minimum essential medium without ribonucleosides and deoxyribonucleosides with 2 mM L-glutamine, 90%; heat-inactivated fetal bovine serum, 10%
|
| Subculturing |
Protocol: - Remove and discard culture medium.
-
Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
-
Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach.
Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. -
Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
-
Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:5 to 1:6 is recommended Medium Renewal: Every 2 to 3 days |
| Cryopreservation |
Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions |
Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37.0°C |
