| Disclosure |
This material is cited in a US or other Patent and may not be used to
infringe the claims. Depending on the wishes of the Depositor, ATCC may be
required to inform the Patent Depositor of the party to which the material was
furnished. This material may not have been produced or characterized by ATCC. |
| Karyotype |
45, XX |
| Derivation |
Cells derived from the tissue were exposed to benzo(a)pyrene, and a transformed line was established. The 184A1 cell line was established from normal mammary tissue obtained from a normal reduction mammoplasty. |
| Clinical Data |
female
21 years |
| Comments |
The line appears to be immortal, but is not malignant.
When seeded at low density, the cells grow as single cells. |
| Complete Growth Medium |
The base medium for this cell line (MEBM) along with the additives can be obtained from Lonza/Clonetics Corporation as a kit: MEGM, Kit Catalog No. CC-3150. ATCC does not use the GA-1000 (gentamycin-amphotericin B mix) provided with kit.
To make the complete growth medium, you will need to add the following components to the kit (sold separately):
- 0.005 mg/ml transferrin
- 1 ng/ml cholera toxin
Note: Do not filter complete medium
|
| Subculturing |
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
- Remove and discard culture medium.
- Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution.
- 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.
- To remove trypsin-EDTA solution, transfer cell suspension to centrifuge tube and spin at approximately 125 x g for 5 to 10 minutes.
Discard supernatant and resuspend cells in fresh serum-free growth medium. Add appropriate aliquots of cell suspension to new culture vessels.
- Place culture vessels in incubators at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:6 is recommended
Medium Renewal: Every 2 to 3 days |
