IM-9
ACC 117
Cell line:
IM-9
DSMZ no.:
ACC 117
Species:
human (Homo sapiens)
Cell type:
B lymphoblastoid cells (from patient with multiple myeloma)
Origin:
established from the bone marrow of a woman with multiple myeloma in 1967; cells were described in the literature to synthesize IgG and to have receptors for insulin and calcitonin; cells express BCL2 mRNA; cells appear to be rather "EBV+ B-lymphoblastoid cells" than myeloma-derived cells (see also Pellat-Deceunynk et al., Blood 86: 4001-4002, 1995), hence NOT a malignant myeloma cell line
Biosafety level:
2
Risk assessment:
The cell line is positive for EBV (HHV-4) by PCR analysis. Additionally, expression of immediate-early protein BZLF-1 was detected by western blot after stimulating the cells with phorbol ester / sodium butyrate. The infection was classified as potentially lytic associated with a possible production of active viruses. A transmission of EBV during handling of the cells is possible and the cell line is thus categorized biosafety level 2.
DSMZ Cell Culture Data:
Medium:
90% RPMI 1640 + 10% h.i. FBS
Subculture:
seed out at ca. 1 x 106 cells/ml; maintain at 1-2 x 106 cells/ml, split 1:2 to 1:3 every 2-3 days; as the medium becomes quickly acidic (yellow) with a corresponding cell growth, it is advisable to change the supernatant medium every 1-2 days
Incubation:
at 37 °C with 5% CO2
Doubling time:
about 45 hours
Harvest:
maximal cell density of 2-2.5 x 106 cells/ml
Storage:
frozen with 70% medium, 20% FBS, 10% DMSO
DSMZ Scientific Data:
Mycoplasma:
negative in DAPI, microbiological culture, RNA hybridization, PCR assays
Immunology:
CD3 -, CD10 -, CD13 -, CD19 +, CD20 +, CD34 -, cyCD79a +, CD80 +, HLA-DR +, cyIgG +, cyIgM -, cykappa +, cylambda -; image
Authenticity:
STR analysis according to the global standard ANSI/ATCC ASN-0002.1-2021 (2021) resulted in an authentic STR profile of the reference STR database.
Cytogenetics:
near diploid - 46(44-46)<2n>XX - apparently normal karyotype
Viruses:
ELISA: reverse transcriptase negative; PCR: EBV +, HBV -, HCV -, HHV-8 -, HIV-1 -, HIV-2 -, HTLV-1/2 -, MLV -, SMRV -
