| Applications |
This cell line is a suitable transfection host. This line has a mutation in codon 12 of the ras proto-oncogene, and can be used as a positive control for PCR assays of mutation in this codon. |
| Storage Conditions | liquid nitrogen vapor phase |
| Karyotype | The stemline chromosome number is hypotriploid and 11-12 marker chromosomes were common. Both double minutes and dicentrics were observed in 8% of each metaphase examined. |

| Comments |
A cell line established from a lymph node metastasis taken from the same patient one year later is available (see ATCCCCL-227). The line is negative for CSAp (CSAp-) and colon antigen 3. The cells are positive for keratin by immunoperoxidase staining. There is a G -> A mutation in codon 273 of the p53 gene resulting in an Arg -> His substitution and a C -> T mutation in codon 309 resulting in a Pro -> Ser substitution. The cells express elevated levels of p53 protein. The line is positive for expression of c-myc, K-ras, H-ras, N-ras, myb, sis and fos oncogenes. N-myc oncogene expression was not detected. Matrilysin, a metalloproteinase associated with tumor invasiveness, is not expressed. The cells have been reported to produce GM-CSF. |
| Complete Growth Medium |
The base medium for this cell line is ATCC-formulated Leibovitz''''''''''''''''''''''''''''''''s L-15 Medium, Catalog No. 30-2008. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
(Note: The L-15 medium formulation was devised for use in a free gas exchange with atmospheric air. A CO2 and air mixture is detrimental to cells when using this medium for cultivation) |
|---|---|
