| Cell line: | SD-1 |
| DSMZ no.: | ACC 366 |
| Species: | human (Homo sapiens) |
| Cell type: | peripheral blood B lymphoblastoid cells (from patient with acute lymphoblastic leukemia) |
| Origin: | established from the peripheral blood of a woman with acute lymphoblastic leukemia (pre B-ALL) at diagnosis; cells were immortalized with EBV; shown at DSMZ by RT-PCR to carry minor breakpoint BCR-ABL1 fusion for which it is a suitable positive control for RT-PCR |
| Reference(s): | 14484, 14458 |
| 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. |
