| 产品名称： | COLO-720L |
|---|---|
| 商品货号： | TS259160 |
| <strong>Cell line </strong>： | COLO-720L |
| DSMZ no. ： | TS259160 |
| Species ： | confirmed as human with IEF of AST, MDH |
| Cell type ： | B lymphoblastoid cells (from patient with adenocarcinoma) |
| Origin ： | B-lymphoblastoid cell line established from the peripheral blood of a 73-year-old woman with metastatic adenocarcinoma in 1988 |
| Reference(s) ： | not published |
| 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. |
| Permissions and restrictions ： | A |
| <strong> </strong>： | DSMZ Scientific Data: |

| Doubling time ： | ca. 20-30 hours |
| Harvest ： | saturation density at about 2.0-2.5 x 106 cells/ml |
| Storage ： | frozen with 70% medium, 20% FBS, 10% DMSO |

| Fingerprint ： | multiplex PCR of minisatellite markers revealed a unique DNA profile |
| Cytogenetics ： | human hyperdiploid karyotype with 10% polyploidy - 47(45-50)<2n>XX, +12, der(5)t(3;5)(p21.3;p15) - the 3p21.3 breakpoint is associated with benign adenoma |
