Storage Conditions | liquid nitrogen vapor phase |
Properties
Karyotype | This is a hypertriploid human cell line. The modal chromosome number is 71, occurring at 34%, and polyploidy at 2.6%. The t(4;11)(p15;q13), i(13q), t(10p15q), del(18)(q21), and 6 other markers are common to most cells, and two other markers are found in some. Giant satellites are seen in one N14, and two N22. N2, N5, and N9 have 4 copies, and N7, N13, N18, N21 and X a single copy. A single Y chromosome is detected by Q-band examination. |

|
Tumorigenic | Yes |
Effects |
Yes, in nude mice; forms malignant tumor consistent with choriocarcinoma
|

Background
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%. |

Subculturing |
Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37¡ãC) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:6 is recommended
Medium Renewal: 2 to 3 times per week
|
Cryopreservation |
Freeze medium: Culture medium, 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
|
Culture Conditions |
