| 产品名称： | WA-OSEL |
|---|---|
| 商品货号： | TS260281 |
| <strong>Cell line </strong>： | WA-OSEL |
| DSMZ no. ： | TS260281 |
| Species ： | human (Homo sapiens) |
| Cell type ： | chronic B cell leukemia |
| Origin ： | established in 1993 from a peripheral blood sample of a Caucasian man with B-type chronic lymphocytic leukemia; CD5 negative sister cell line of WA-C3CD5+ (DSM ACC 769) |
| Reference(s) ： | 19334, 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. |
