NAMALWA.CSN/70
ACC 70
Cell line:
NAMALWA.CSN/70
DSMZ no.:
ACC 70
Species:
human (Homo sapiens)
Cell type:
Burkitt lymphoma
Origin:
established from the tumor mass of a boy with Burkitt lymphoma; this variant subline from the original NAMALWA (ACC 24) was described in the literature to be characterized by differential expression of immunoglobulin and MYC genes and of certain cell surface antigens (see reference); cells were reported to harbor a retrovirus of simian origin, SMRV-H
Reference(s):
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. Additionally, this cell line carries sequences of the squirrel monkey retrovirus (SMRV). 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.
