Tumorigenic:No
Age: newborn
Comments:The line is sensitive to promotion of transformation (P+) by phorbol esters and other tumor promoters; this is one of several lines that are useful in studies of the molecular events in tumor promotion and for development of promotion assays (see also ATCC CRL-2007 - JB6 Cl 30-7b, ATCC CRL-2002 - RT101 and ATCC CRL-2012 - T36274).
The JB6 Cl 41-5a cell line was established from primary cultures of neonatal BALB/c epidermal cells that had been treated with dimethylsulfoxide (DMSO, 0.01 to 0.1 %).
The cells must be carried at low density to avoid spontaneous transformation.
The cells should be subcultured for at least two passages prior to testing in agar for tumor promotor induced transformation.
For the Anchorage Independent Transformation Assay, suspend 10000 cells in 0.33% agar medium containing 8% fetal bovine serum, with or without added tumor promoter (e.g., 10 ng/ml TPA).
Incubate at 37C, and score colonies greater than 8 cells at 14 days.
Propagation: ATCC complete growth medium: Minimum essential medium (Eagle) with 2 mM L-glutamine and Earle's BSS adjusted to contain 1.5 g/L sodium bicarbonate, 0.1 mM non-essential amino acids, and 1.0 mM sodium pyruvate, 95%; heat-inactivated fetal bovine serum, 5%
Temperature: 37.0°C
Subculturing: Protocol: Remove medium, rinse with fresh 0.25% trypsin, 0.53 mM EDTA solution, remove the trypsin solution and let the culture sit at room temperature (or at 37C) until the cells detach (about 5 TO 15 minutes). Add fresh medium, aspirate and dispense into new flasks. Do not allow the cells to become confluent.
Subcultivation Ratio: An inoculation density of 2 X 10 exp4 viable cells per 25 sq. cm. flask is recommended
Medium Renewal: 2 to 3 times per week
Preservation: Culture medium with an additional 5% fetal bovine serum, 95%; DMSO, 5%
Related Products:Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
