Oncogene:E6/E7 +
Antigen Expression:epithelial specific antigen
Age: 133 days gestation
Comments:Passage 2 cells were transformed with a retrovirus vector ( LXSN16E6E7 produced by ATCC CRL-2203 ) in the presence of polybrene.
This line stains positively with antibody for cytokeratin.
After 50 population doublings, the cells continue dividing and retain cuboidal morphology.
E6E7 sequences were detected by PCR in cells at passage 18.
Major Histocompatibility Complex class I or II molecules were not expressed on these cells, but PCR analyses revealed presence of the genes for directing synthesis of HLA antigens.
Epithelial specific antigen was detected using antibody produced by the Ep16 hybridoma (ATCC HB-155 ).
Propagation:
ATCC complete growth medium: These cells are grown in Keratinocyte-Serum Free Medium (Gibco 17005-042)supplemented with
-
0.05 mg/ml bovine pituitary extract (BPE)
-
35 ng/ml human recombinant epidermal growth factor (EGF)
Do not filter complete medium.
Temperature: 37.0°C
Add fresh medium twice per week
Subculturing:
Protocol: Remove medium, rinse two times with cold 0.25% trypsin, 0.03% EDTA solution. Allow the flasks to sit at room temperature (or incubate at 37C) until the cells detach. Neutralize the trypsin with fresh culture medium, centrifuge, resuspend cells in fresh culture medium and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:5 is recommended
Medium Renewal: Add fresh medium twice per week
Preservation:
Freeze medium: Ham's F12 medium 85%; DMSO, 5%; FBS 10%
Storage temperature: liquid nitrogen vapor phase
