ARH-77
ACC 512
Cell line:
ARH-77
DSMZ no.:
ACC 512
Species:
human (Homo sapiens)
Cell type:
B lymphoblastoid cells
Origin:
established from the peripheral blood of a 33-year-old woman with IgG plasma cell leukemia; cell line is widely used as model for multiple myeloma/plasma cell leukemia, but cells are clearly EBV+ indicating that ARH-77 might be rather a "normal" B-lymphoblastoid cell line than a tumor cell line
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.
