| 商品货号: | TS259481 |
| <strong>Cell line </strong>: | SD-1 |
| DSMZ no. : | TS259481 |
| Species : | confirmed originally as human with IEF of AST, LDH, NP later by STR fingerprinting |
| 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. |
