Isolation: Rockville Maryland, United States
Isolation date: November, 1995
Oncogene:E6/E7 +
Antigen Expression:epithelial specific antigen; Homo sapiens, expressed (Epithelial specific antigen was detected using antibody produced by the Ep16 hybridoma (ATCC HB-155 ).) (Epithelial specific antigen was detected using antibody produced by the Ep16 hybridoma (ATCC HB-155 ).)
Cytogenetic Analysis:hyperdiploid; about 55% of cells contain 45 to 50+ chromosomes
Isoenzymes: G6PD, A-B (This lines has a rare human G6PD phenotype (A-B).)
Age: 112 days gestation fetus
Comments: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.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.
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.
Atmosphere: air, 95%; carbon dioxide (CO2), 5%
Temperature: 37.0°C
Subculturing:
Protocol: Remove medium, rinse two times with cold 0.25% trypsin, 0.53 mM 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 F12K medium, 85%; fetal bovine serum, 10%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
