| Depositor: | CLS |
| Organism: | Homo sapiens (human) |
| Ethnicity: | caucasian |
| Age/Stage: | 58 years; Duke's type B |
| Gender: | female |
| Tissue: | Colon, colorectal |
| Morphology: | epithelial |
| Celltype: | adenocarcinoma |
| Description: | The cells are positive for Colon Antigen 3. They are negative for p53 antigen expression, but positive for mRNA expression. The line was derived from the same tumor as LS 180. LS 174T cells stain positively for cytokeratins. |
| Culture Medium: | Minimum essential medium (Eagle) in Earle's BSS supplemented with 2 mM L-glutamin, 1% non-essential amino acids and 10% fetal bovine serum (MG-10, CLS order number 820100). |
| Subculturing: | Remove medium and rinse the adherent cells using PBS without calcium and magnesium (3-5 ml PBS for T25, 5-10ml for T75 cell culture flasks). Add Accutase (1-2ml per T25, 2.5ml per T75 cell culture flask), the cell sheet must be covered completely. Incubate at 37°C for 10 minutes. Carefully resuspend the cells, the addition of medium is optional but not necessary, and dispense into new flasks which contain fresh medium. |
| Split Ratio: | A ratio of 1:2 to 1:5 is recommended |
| Fluid Renewal: | 2 to 3 times weekly |
| Freeze Medium: | CM-1 (CLS order number: 800125, 25ml, 800150, 50ml) |
| Sterility: | Tests for mycoplasma, bacteria and fungi were negative |
| Biosafety Level: | 1 |
