Cell line: | U2OS#18-RAD51C-15/C+ |
DSMZ no.: | ACC 839 |
Species: | human (Homo sapiens) |
Cell type: | osteosarcoma |
Origin: | Genetical modification of U2OS#18 (DSMZ ACC 832), a reporter cell line for studying sister chromatid recombination, SCR). This cell line belongs to the series of genetically disrupted RAD51 paralogs with reversion of the disruption by retroviral transfection with the functional gene (the non-complemented sister cell line is ACC 834). Cells are described in the literature to be puromycin and hygromycin resistant |
Reference(s): | 18169, 18205, 18186 |
Biosafety level: | 1, GMO-S1 |
Risk assessment: | genetically modified organism, according to German and European legislation allocated into group S1 |
Permissions and restrictions: | A, D |
Depositor-specific restrictions: | Transfer to third parties needs to be negotiated with the depositor. |
| DSMZ Cell Culture Data: |
Morphology: | epithelioid cells growing adherently as monolayer; image; image |
Medium: | 90% DMEM + 10% h.i. FBS + (additionally) 2 mM L-glutamine (to verify antibiotic resistance, 1 µg/ml puromycin and/or 150 µg/ml hygromycin should be added) |
Subculture: | seed out at 1 x 106 cells/175 cm2;
split confluent culture 1:4 to 1:10 every 4-10 days using trypsin/EDTA |
Incubation: | at 37 °C with 10% CO2 |
Doubling time: | ca. 25-40 hours |
Harvest: | cell harvest of 15-25 x 106 cells/175 cm2 flask |
Storage: | frozen with 70% medium, 20% FBS, 10% DMSO |
| DSMZ Scientific Data: |
Mycoplasma: | negative in PCR assay |
Immunology: | to inquire about expression of EpCAM and intermediate filaments, contact ulfert.rand@dsmz.de. |
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. |
Molec. Genetics: | frameshift mutations in exon 1 of RAD51C were verified by sequence analysis and forced expression of RAD51C in the retrovirally transfected cell line was confirmed by RQ-PCR analysis |
Viruses: | PCR: EBV -, HBV -, HCV -, HIV-1 -, HIV-2 -, HTLV-1/2 -, MLV - |
