| Cell line: | RAJI |
| DSMZ no.: | ACC 319 |
| Species: | human (Homo sapiens) |
| Cell type: | Burkitt lymphoma |
| Origin: | established from the left maxilla of a 12-year-old boy with Burkitt lymphoma in 1963; first continuous human hematopoietic cell line; cells carry a t(8;14) translocation leading to MYC-IGH fusion gene. Exome and RNA sequence data are available (see Ref 18187 and
Exome sequence
and RNA-Seq) |
| Reference(s): | 14862, 15231, 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 and lately expressed capsid protein were negative by western blot and immunostaining, respectively, 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 Central Committee for Biological Safety (ZKBS) and in contrast to other EBV infected cell lines, the cells can be handled under biosafety level 1 when the cells are used in genetic engineering projects. |
