| Disease： | Lymphoma |
| Applications： | The line was produced by fusing A20.2J lymphoma cells (I-Ad, I-Ed) with T cell depleted spleen cells from C57BL/10 mice (I-Ab, I-Eb). Tested and found negative for ectromelia virus (mousepox). |
| Derivation： | The line was produced by fusing A20.2J lymphoma cells (I-Ad, I-Ed) with T cell depleted spleen cells from C57BL/10 mice (I-Ab, I-Eb). |
| Comments： | The LB 27.4 bears surface I-Ad,b/d,b and I-Ed,d/b molecules and can present antigen to appropriate I region restricted T cell hybridomas. The line was produced by fusing A20.2J lymphoma cells (I-Ad, I-Ed) with T cell depleted spleen cells from C57BL/10 mice (I-Ab, I-Eb). Tested and found negative for ectromelia virus (mousepox). |
| Complete Growth Medium： | The base medium for this cell line is ATCC Hybri-Care Medium, Catalog No. 46-X. Hybri-Care Medium is supplied as a powder and should be reconstituted in 1 L cell-culture-grade water. To make the complete growth medium, add the following components to the base medium:
|
| Subculturing： | Medium Renewal: Every 2 to 3 days Cultures can be maintained by addition or replacement of fresh medium. Start cultures at 1 X 10 exp5 cells/ml and maintain between 1 X 10 exp5 and 1 X 10 exp6 cells/ml. |
| Cryopreservation： | Freeze medium: complete growth medium, 95%; DMSO, 5% |
