| Cell line: | NCEB-1 |
| DSMZ no.: | ACC 721 |
| Species: | human (Homo sapiens) |
| Cell type: | B cell lymphoma |
| Origin: | established in 1987 by Epstein-Barr virus (EBV) transformation of neoplastic peripheral blood cells from a 57-year-old man with centroblastic-centrocytic diffuse B-cell non-Hodgkin lymphoma (B-NHL; mantle cell lymphoma); cells stably carry 5-8 mouse chromosomes and a t(11;14) leading to alteration of CCND1 (BCL1) and IGH genes |
| Reference(s): | 16466, 16467, 16468, 15229 |
| Biosafety level: | 2 |
| Risk assessment: | The cell line is positive for EBV (HHV-4) by PCR analysis. Additionally, expression of immediate-early protein BZLF-1 was also positive by western blot in untreated and phorbol ester / sodium butyrate stimulated cells. The infection was classified as lytic associated with a production of active viruses. A transmission of EBV during handling of the cells is possible and the cell line is thus categorized biosafety level 2. |
