human (Homo sapiens)
natural killer lymphoma
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.
Permissions and restrictions:
For-profit organizations require a license from the owner of the cell line prior of its use. The material or its products must not be transferred to third parties for any reason. Any proposed commercial use of these cells must first be negotiated with: ImmunityBio, Inc.
DSMZ Cell Culture Data:
75% alpha-MEM (with ribo- and deoxyribonucleosides) + 12.5% h.i. FBS + 12.5 % h.i. horse serum + 2 mM L-glutamine + 5 ng/ml IL-2
seed out at ca. 0.5 x 106 cells/ml; maintain at 0.2-0.6 x 106 cells/ml; split saturated culture 1:2 every 2 days; after thawing, it is recommended to first culture the cells in 24-well-plates; viability may not surpass 60-70%; cells grow mainly in large clusters, outside these clusters a significant amount of cell debris and dead cells are always visible

ca. 40-50 hours
maximum density of about 0.8 x 106 cells/ml
frozen with 70% medium, 20% FBS, 10% DMSO
