| Cell line: | LCL-HO |
| DSMZ no.: | ACC 185 |
| Species: | human (Homo sapiens) |
| Cell type: | B lymphoblastoid cells (from patient with melanoma) |
| Origin: | this lymphoblastoid cell line was established by EBV transformation of peripheral blood lymphocytes; cell line was submitted as autologous to cell line MEL-HO (DSM ACC 62) that was derived from a woman with primary melanoma in 1976; however, cytogenetic and DNA fingerprinting analysis showed clearly that LCL-HO and MEL-HO are not related |
| 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. 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. |
