Cell line: | EB-1 |
DSMZ no.: | ACC 80 |
Species: | human (Homo sapiens) |
Cell type: | Burkitt lymphoma |
Origin: | established from the maxilla tumor lymph node of a 9-year-old girl with Burkitt lymphoma in 1964; cells were described in the literature to be EBV-positive |
Reference(s): | 14518, 14519, 14520 |
Biosafety level: | 2 |
Risk assessment: | The cell line is positive for EBV (HHV-4) by PCR analysis. Additionally, expression of immediate-early protein BZLF-1 was also positive by western blot analysis in untreated and phorbol ester / sodium butyrate stimulated cells. The infection was classified as lytic associated with a production of active viruses. A transmission of EBV during handling of the cells is possible and the cell line is therefore classified biosafety level 2. |
