Cell line:
DSMZ no.:
ACC 48
human (Homo sapiens)
Cell type:
B cell lymphoma
established in 1996 from the diagnostic pre-treatment pleural effusion sampled preterminally of a 49-year-old HIV+ man with primary effusion lymphoma (PEL) and previous history of Kaposi's sarcoma; autopsy revealed involvement of serous membranes without formation of solid tumor mass; cells were described in the literature to be EBV+, HHV-8+ and to carry a BCL6 point mutation
15032, 14417, 14483
Biosafety level:
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. Additionally, the cell line carries HHV-8 sequences which were detected by PCR and Southern blot. We did not determine the infection mode of this herpes virus and cannot exclude the secretion of the viruses. The cell line is thus categorized biosafety level 2.

DSMZ Cell Culture Data:
lymphoblast-like cells growing in clumps or as single cells in suspension
80% RPMI 1640 + 20% h.i. FBS
seed out after thawing at ca. 0.5 x 106 cells/ml; split saturated culture about 1:2 to 1:3 every 2-4 days; maintain at ca. 0.2-0.5 x 106 cells/ml feeding cultures daily; viability decreases dramatically after thawing, however cells recover within 1-2 weeks but will not exceed 80%; cells are sensitive to freezing methods, best results are obtained with a constant cooling rate to -196°C; cooling to -80°C applying a box with isopropanol and subsequent transfer to liquid nitrogen is not recommended
at 37 °C with 5% CO2
Doubling time:
ca. 3-4 days
maximal density at ca. 1.5 x 106 cells/ml
frozen with 70% medium, 20% FBS, 10% DMSO
