| Cell line: | BC-2 |
| DSMZ no.: | ACC 678 |
| Species: | human (Homo sapiens) |
| Cell type: | B cell lymphoma |
| Origin: | established in 1992 from the malignant effusion samples of a 31-year-old man at diagnosis of AIDS-related primary effusion lymphoma (PEL); cells are reported to be positive for human herpesvirus type 8 (HHV-8) and Epstein-Barr virus (EBV) while negative for human immunodeficiency virus (HIV) and human T-cell leukemia virus I/II (HTLV-I/II) |
| Reference(s): | 14483, 15928, 15929 |
| Biosafety level: | 2 |
| Risk assessment: | The cell line carries HHV-8 sequences which were detected by PCR and Southern blot. We did not determine the infection mode of this herpes virus and cannot exclude the secretion of the viruses. The cell line is also positive for EBV (HHV-4) by PCR analysis. Additionally, expression of immediate-early protein BZLF-1 and lately expressed capsid protein were also positive by western blot and immunostaining, respectively, in untreated and phorbol ester / sodium butyrate stimulated cells. The infection was classified as lytic associated with 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. |
