| 产品名称： | T2 |
|---|---|
| 商品货号： | TS259931 |
| <strong>Cell line </strong>： | T2 |
| DSMZ no. ： | TS259931 |
| Species ： | confirmed as human by species PCR |
| Cell type ： | somatic cell hybrid |
| Origin ： | established by PEG-mediated fusion of the B-lymphoblastoid cell line (B-LCL) LCL 721.174 with an 8-azaguanine and ouabain-resistant variant of the T-LCL CEM (CEMR.3); cells were described in the literature to synthesize HLA-A2 and -B5 RNA, but express only small amounts of A2 and no B5 antigen on the cell surface; subclone of the T1 cell line which has lost both CEMR-derived copies of chromosome 6; cell line also known as 174xCEM.T2 |
| Reference(s) ： | 14914, 14915 |
| 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. |
