| Applications |
This cell line is a suitable transfection host. |
| Storage Conditions |

| Karyotype |
The stemline chromosome number is hyperdiploid with the 2S component occurring at about 2.7% and 3 marker chromosomes were common to all S metaphases. Karyotypes were generally homogeneous and stable. |
| Derivation |
LoVo was initiated in 1971 from a fragment of a metastatic tumor nodule in the left supraclavicular region of a 56-year-old Caucasian male patient with a histologically proven diagnosis of adenocarcinoma of the colon. |

| Genes Expressed |
carcinoembryonic antigen (CEA) 908 ng/10 6 cells/10 days. The cells are negative for expression of CSAp (CSAp-) and colon antigen 3. |
| Cellular Products |
carcinoembryonic antigen (CEA) 908 ng/10 exp6 cells/10 days |
| Tumorigenic |
Yes |
| Effects |
Yes, in nude mice (Tumors developed within 21 days at 100% frequency (5/5) in nude mice inoculated subcutaneously with 10(7) cells) |
| Comments |
The cells are negative for expression of CSAp (CSAp-) and colon antigen 3.
The line is positive for expression of c-myc, K-ras, H-ras, N-ras, Myb, sis and fos oncogenes.
N-myc and sis oncogene expression were not detected.
Tumor specific nuclear matrix proteins CC-3 and CC-4 are expressed. |
| Complete Growth Medium |
The base medium for this cell line is ATCC-formulated F-12K Medium, Catalog No. 30-2004. 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-0.53mM 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 1:3 to 1:10 is recommended
Medium Renewal: 2 to 3 times per week
