Comments: The DB cell line was established by Walter J. Urba and Dan L. Longo from ascites fluid from a patient with a diffuse large cell lymphoma.
DB細胞The cells do not express HLA-DR, HLA-DQ, IgM , IgD or T cell rantigen receptor.
Exposure of DB cells to phorbol esters (PMA or PdBu) that activate protein kinase C results in profound growth inhibition.
They are reported to be negative for the Epstein-Barr virus genome.
The cells were cured of a prior mycoplasma contamination by a 21 day treatment with BM-cycline.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. 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: Protocol: Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 5 to 8 X 10 exp5 cells/ml and maintain between 5 X 10 exp5 and 2 X 10 exp6 cells/ml.
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium, 90%; DMSO, 10%
Storage temperature: liquid nitrogen vapor phase
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2001
recommended serum:ATCC 30-2020
