| Cell line: | IARC-304 |
| DSMZ no.: | ACC 897 |
| Species: | human (Homo sapiens) |
| Cell type: | B lymphoblastoid cells |
| Origin: | B-lymphoblastoid cell line established in 1979 from normal B-cells from bone marrow of a 7-year old boy with non-endemic Burkitt lymphoma; autologous Burkitt lymphoma cell line BL-2 is available (DSMZ ACC 625) |
| Reference(s): | 40200, 14714 |
| Biosafety level: | 1 |
| Risk assessment: | The cell line is positive for EBV (HHV-4) by PCR analysis. However, expression of immediate-early protein BZLF-1 was negative by western blot in untreated and phorbol ester / sodium butyrate stimulated cells. The infection was classified as latent infection without production of active viruses. A transmission of EBV during handling of the cells is unlikely and thus the cell line is categorized biosafety level 1.
According to a recommendation of the German Central Committee for Biological Safety (ZKBS) the cells have to be handled under biosafety level 2 when the cells are used in genetic engineering projects. |
