| Derivation | The SK-N-BE(2) neuroblastoma cell line was established in November of 1972 from a bone marrow biopsy taken from child with disseminated neuroblastoma after repeated courses of chemotherapy and radiotherapy. |
| Clinical Data | male
2 years |
| Tumorigenic | Yes |
| Effects | Yes, an inoculum of 107 cells produced tumors in cortisonized hamster cheek pouches with 18% frequency |
| Comments | The cells exhibit moderate levels of dopamine beta hydroxylase activity.
SK-N-BE(2) cells have a reported saturation density greater than 1 X 106 cells/cm2.
The morphology of the cells varies with some cells having long processes and others that are epithelioid like.
The cells will aggregate, form clumps and float. |
| Complete Growth Medium | The base medium for this cell line is a 1:1 mixture of ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003, and F12 Medium. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
|
| Subculturing | These cells grow as a mixture of floating and adherent cells. Remove the medium with the floating cells, and recover the cells by centrifugation. Rinse the adherent cells with a fresh 0.25% trypsin, 0.53 mM EDTA solution, add an additional 1 to 2 mL of trypsin solution, and let the culture sit at room temperature (or at 37°C) until the cells detach. Add fresh medium, aspirate, combine with the floating cells recovered above and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:12 to 1:20 is recommended.
Medium Renewal: Every 4 to 7 days. |
| Cryopreservation | Freeze medium: Complete growth medium, 95%; DMSO, 5% Storage temperature: liquid nitrogen vapor phase |
| Culture Conditions | Temperature: 37°C |
