293/CHE-Fc细胞Isolation: Isolation date: 1996
Receptors: androgen receptor, expressed
Tumorigenic: Yes
Age: *****
Gender: male
Comments: The TRAMP-C1 (ATCC - CRL-2730), TRAMP- C2 (ATCC -CRL-2731) and TRAMP-C3 (ATCC CRL-2732) cell lines were derived in 1996 from a heterogeneous 32 week primary tumor in the prostate of a PB-Tag C57BL/6 (TRAMP) mouse. TRAMP is a transgenic line of C57BL/6 mice harboring a construct comprised of the minimal -426/+28 rat probasin promoter (426 base pairs of the rat probasin (PB) gene promoter and 28 base pairs of 5'-untranslated region) to target expression of the SV40 large T antigen to prostatic epithelium. Neither the cells grown in culture, nor the tumors arising from the cells in vivo, express SV40 T antigen (Tag). TRAMP-C1 and TRAMP-C2 are tumorigenic when grafted into syngeneic C57BL/6 hosts. However, TRAMP-C3 grows readily in vitro, but does not form tumors. These cell lines represent various stages of cellular transformation and progression to androgen-independent metastatic disease that can be manipulated in vitro. The cell lines can be used in studies to elucidate molecular mechanisms associated with the initiation, progression and metastasis of prostate cancer. They are also a useful tool for gene/drug discovery.
Propagation: ATCC complete growth medium: Dulbecco's modified Eagle's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate and 4.5 g/L glucose supplemented with 0.005 mg/ml bovine insulin and 10 nM dehydroisoandrosterone, 90%; fetal bovine serum, 5%; Nu-Serum IV, 5%.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Subculturing: 293/CHE-Fc细胞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 1:6 to 1:10 is recommended
Medium Renewal: Two to three times weekly
Preservation: Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO
Storage temperature: liquid nitrogen vapor phase
Doubling Time: 25 hrs
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2002
recommended serum:ATCC 30-2020
