| Karyotype |
modal number = 22; range = 20 to 23, Pseudodiploid. The rate of higher ploidies was 4%. Twelve to fourteen marker chromosomes were common to most cells. These include 1p-, 4q+, 4p+, t(6,?), 7q+ and seven to eight other small markers., Normal N2 and N3 were paired; N1, N5, N6 and N10 were single. Normal X and Y were absent, but a single Xq- was present in every cell. |
| Derivation |
In 1966, E.H.Y. Chu obtained the line from W. Sinclair, and isolated the V79-4 clone. This cell line was developed by Ford and Yerganian in 1958 from lung tissue of a young male Chinese hamster, and was originally designated Strain V. A culture at passage 7 after cloning was submitted to the ATCC in July 1988. |
| Clinical Data |
male
|
| Comments |
The cells have a high plating efficiency (80%), and a generation time of 12 to 14 hours.
The line was renamed V79 by Elkind in 1958. |
| Complete Growth Medium |
The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| 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.
