| <strong>Cell line </strong>: | B95-8 |
| DSMZ no. : | TS258958 |
| Species : | Sanguinus oedipus origin confirmed by COI DNA barcoding |
| Cell type : | lymphocytes |
| Origin : | established from peripheral blood lymphocytes of a cotton-top tamarin (cotton-top marmoset) monkey (Saguinus oedipus); cells were described in the literature to release high titers of Epstein-Barr virus (EBV) providing a source for transformation of B cells and establishment of continuous cell lines |
| Reference(s) : | 14764, 14765 |
| 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 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 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. |
