| Species: | human (Homo sapiens) |
| Cell type: | B cell precursor leukemia |
| Origin: | established from the peripheral blood of a 15-year-old girl with acute lymphoblastic leukemia (ALL at first relapse) in 1973; carries t(12;21) leading to ETV6-RUNX1 (TEL-AML1) fusion gene. Exome and RNA sequence data are available (see Ref 18187 and

| | DSMZ Cell Culture Data: |
| Morphology: | small, round, single cells in suspension; image; image; image; image; image; image |
| Medium: | 90% RPMI 1640 + 10-20% h.i. FBS |
| Subculture: | cells may be difficult to culture! seed out at ca. 2 x 106 cells/ml with initially 20% FBS in a 24-well plate; cells can be maintained at high density (>2 x 106 cells/ml); minimum density at ca. 0.5 x 106 cells/ml; cells grow slowly; after thawing viability may decreases during the first days, but cells recover afterwards; do not change medium during this time |
| Incubation: | at 37 °C with 5% CO2 |
| Doubling time: | ca. 50-70 hours |
| Harvest: | maximum density at ca. 3-5 x 106 cells/ml or higher |
| Storage: | frozen with 70% medium, 20% FBS, 10% DMSO |
| | DSMZ Scientific Data: |
| Mycoplasma: | initial contamination was eliminated with Ciprobay (ciprofloxacin), then negative in DAPI, microbiological culture, RNA hybridization, and continuously in PCR assays |
| Immunology: | CD3 -, CD10 +, CD13 -, CD19 +, CD34 -, CD37 -, CD38 +, cyCD79a+, CD80 -, CD138 +, HLA-DR +, sm/cyIgG -, sm/cyIgM -, sm/cykappa -, sm/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: | human pseudodiploid karyotype - 46(44-47)<2n>X, -X, +16, del(3)(p22), t(4;12;21;16)(q32;p13;q22;q24.3)-inv(12)(p13q22), t(5;12)(q31-q32;p12), der(16)t(16;21)(q24.3;q22) - sideline with inv(5)der(5)(p15q31),+18 - carries t(12;21) and del(12) producing respective ETV6-RUNX1 (TEL-AML1) fusion and deletion of residual ETC6 (TEL) |
| Molec. Genetics: | expression of fusion gene ETV6-RUNX1 (TEL-AML1) confirmed by RT-PCR |
