Comments: 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. [1049]
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. [22861]
Myb, and fos oncogenes. [22861]
N-myc and sis oncogene expression were not detected. [22861]
Tumor specific nuclear matrix proteins CC-3 and CC-4 are expressed. [23341]
Propagation:  ATCC 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%.
Temperature: 37.0°C
Subculturing:  Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:10 is recommended
Medium Renewal: 2 to 3 times per week
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 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Preservation:  culture medium 95%; DMSO, 5%
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2004
recommended serum:ATCC 30-2020
