| <strong>Cell line </strong>: | PG-EBV |
| DSMZ no. : | TS260305 |
| Species : | human (Homo sapiens) |
| Cell type : | B lymphoblastoid cells |
| Origin : | normal B-cell derived lymphoblastoid cell line established in 1988 from a man with chronic lymphocytic leukemia (CLL) by immortalization with B95-8 derived EBV; autologous to cell line PGA-1 (DSM ACC 766); cell line is also known as PG/B95-8 |
| Reference(s) : | 19170, 19171, 19172 |
| 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 Commission for Biosafety (ZKBS) the cells have to be handled under biosafety level 2 when the cells are used for genetic manipulations. |
