| 产品名称： | PGA-1 |
|---|---|
| 商品货号： | TS260286 |
| <strong>Cell line </strong>： | PGA-1 |
| DSMZ no. ： | TS260286 |
| Species ： | human (Homo sapiens) |
| Cell type ： | chronic B cell leukemia |
| Origin ： | established in 1988 from leukemic B cells of a Caucasian man with chronic lymphocytic leukemia (CLL); cells are described in the literature to be in vivo EBV-infected. Exome and RNA sequence data are available (see Ref 18187 and Exome sequence and RNA-Seq) |
| Reference(s) ： | 19170, 19171, 19172, 18187 |
| 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. |
