Designations:BT-20
Depositors:EY Lasfargues
Biosafety Level:1
Shipped:frozen
Medium & Serum:See Propagation
Growth Properties:adherent
Organism:Homo sapiens
Morphology:epithelial
 
Source:Organ: mammary gland; breast 
Disease: carcinoma
Permits/Forms:In addition to the MTA mentioned above, other ATCC and/or regulatory permits may be required for the transfer of this ATCC material. Anyone purchasing ATCC material is ultimay responsible for obtaining the permits. Please click here for information regarding the specific requirements for shipment to your location.
Isolation:Isolation date: 1958
Applications:BT-20 cells are negative for estrogen receptor, but do express an estrogen receptor mRNA that has deletion of exon 5. 
This breast tumor line was established by E.Y. Lasfargues and L. Ozzello in 1958 by isolation and cultivation of cells spilling out of the tumor when it was cut in thin slices.
Tumorigenic:Yes

This breast tumor line was established by E.Y. Lasfargues and L. Ozzello in 1958 by isolation and cultivation of cells spilling out of the tumor when it was cut in thin slices. A mycoplasma contaminant was discovered and eliminated early in 1972. 
Growth of BT-20 cells is inhibited by tumor necrosis factor alpha (TNF alpha). 
BT-20 cells are negative for estrogen receptor, but do express an estrogen receptor mRNA that has deletion of exon 5.
Propagation:ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Atmosphere: air, 95%; carbon dioxide (CO2), 5% 
Temperature: 37.0°C
Subculturing:Protocol:
  1. Remove and discard culture medium.
  2. 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.
  3. 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.
  4. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 37°C.

Subcultivation Ratio: A subcultivation ratio of 1:2 to 1:4 is recommended 
Medium Renewal: 2 to 3 times per week
Preservation:Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO 
Storage temperature: liquid nitrogen vapor phase
Related Products:Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
recommended serum:ATCC 30-2020
