| Derivation | 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. |
| Clinical Data | 45 years
Caucasian
male
|
| Antigen Expression | CD19 +; CD20 +; CD22 +; Hle-1 +; CD21 -; CD25 - |
| Cellular Products | immunoglobulin |
| Comments | 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. |
| Complete Growth Medium | The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%.
|
| Subculturing | Cultures can be maintained by addition of fresh medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 5 x 105 viable cells/mL. Maintain cultures at a cell concentration between 5 x 105 and 2 x 106 cells/mL. Do not allow the cell concentration to exceed 2 x 106 cells/mL. Medium Renewal: 2 to 3 times weekly. |
| Cryopreservation | Freeze Medium: Complete growth medium, 90%; DMSO, 10%
Storage Temperature: Liquid nitrogen vapor phase |
| Culture Conditions | Temperature: 37°C |
| STR Profile | Amelogenin: X,Y CSF1PO: 10,11 D13S317: 11,12 D16S539: 11 D5S818: 11 D7S820: 11 THO1: 6,8 TPOX: 8 vWA: 15,16 |
