| 商品货号: | TS260377 |
| <strong>Cell line </strong>: | GH |
| DSMZ no. : | TS260377 |
| Species : | confirmed as human by STR-typing |
| Cell type : | testicular germ cell tumor |
| Origin : | established in 1980 from a human testicular teratocarcinoma of a male patient of unknown age; cells are described in the literature to express mRNA for endogenous retrovirus and virus-like particles; they are further described in the literature to be ultrasensitive to cisplatin |
| Reference(s) : | 18139, 18140, 18141, 15195 |
| Biosafety level : | 2 |
| Risk assessment : | As described in literature, the GH cells produce human teratocarcinoma derived viruses (HDTV) which are identical to human endogenous retrovirus K (HERV-K). HERV-K is assigned to biosafety level 2 in Germany. The cell culture supernatant shows a marginal reverse transcriptase activity in the cell culture supernatant which can slightly be stimulated by 5-azacytidine and strongly applying 5-iodo-2-deoxyuridine. The activity was determined employing the product enhanced reverse transcriptase assay (PERT) |

| Medium : | 80% RPMI 1640 + 20% h.i. FBS |
| Subculture : | seed out at ca. 1-2 x 106 cells/175 cm2 flask; split confluent culture 1:2 - 1:4 once or twice a week using trypsin/EDTA |

| Doubling time : | ca. 50 hours |
| Harvest : | cell harvest of ca. 8 x 106 cells/175 cm2 |
| Storage : | frozen with 70% medium, 20% FBS, 10% DMSO |
| Mycoplasma : | negative in PCR assay |
| Immunology : | to inquire about expression of EpCAM and intermediate filaments, contact hilmar.quentmeier@dsmz.de. |
