Biosafety Level |
2
Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country. |
Storage Conditions |
liquid nitrogen vapor phase |
Derivation |
This line was originally thought to be derived from normal amnion, but was subsequently found, based on isoenzyme analysis, HeLa marker chromosomes, and DNA fingerprinting, to have been established via HeLa cell contamination. |
Antigen Expression |
The cells are positive for keratin by immunoperoxidase staining. |
HeLa Markers |
Y |
Genes Expressed |
The cells are positive for keratin by immunoperoxidase staining.
The cells and tumors formed from the cells are positive for Dopa decarboxylase and are negative for the TAG-72 antigen. |
Cellular Products |
keratin |
Virus Susceptibility |
Human poliovirus 1
Human poliovirus 2
Human adenovirus 3
Vesicular stomatitis virus

Comments |
NOTE: Cells of this line contain HeLa marker chromosomes, and were derived via HeLa contamination

Complete Growth Medium |
EMEM (30-2003) supplemented with 10% FBS (30-2020) |
Subculturing |
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium 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 to remove all traces of serum which 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 1:2 to 1:10 is recommended
Medium Renewal: Twice per week
