Cell line: | DAUDI |
DSMZ no.: | ACC 78 |
Species: | human (Homo sapiens) |
Cell type: | Burkitt lymphoma |
Origin: | established from the Burkitt lymphoma (left orbital biopsy) of a 16-year-old boy in 1967; cells were described in the literature to be EBV-positive and to express mRNA for proto-oncogene BCL2. Exome and RNA sequence data are available (see Ref 18187 and
Exome sequence
and RNA-Seq) |
Reference(s): | 14668, 14794, 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) the cells have to be handled under biosafety level 2 when the cells are used in genetic engineering projects. |
