HEK293-DR-GFP-XRCC2-13
ACC 848
Cell line:
HEK293-DR-GFP-XRCC2-13
DSMZ no.:
ACC 848
Species:
human (Homo sapiens)
Cell type:
embryonal kidney
Origin:
Genetic modification of HEK293-DR-GFP (DSMZ ACC 844, a hprtDR-GFP reporter cell line for studying chromosomal double-strand repair (DR)). This cell line carries a genetic disruption of XRCC2 by frameshifting mutations in exon 3 (targeted by CRISPR-CAS9) and is puromycin resistant. The wild-type allele is no longer present. A sister cell line with the retrovirally reconstituted XRCC2
gene is available as ACC 853
Biosafety level:
1, GMO-S1
Risk assessment:
genetically modified organism, according to German and European legislation allocated into group S1
Depositor-specific restrictions:
Transfer to third parties needs to be negotiated with the depositor.
DSMZ Cell Culture Data:
Morphology:
Medium:
90% DMEM + 10% h.i. FBS + (additionally) 2 mM L-glutamine (to sustain genetic stability cells should be maintained, at least periodically, with 0.5 µg/ml puromycin)
Subculture:
culture vessels should be coated with 0.01% poly-L-lysine solution; seed out at 1 x 106 cells/25 cm2; split 1:2 to 1:4 every 2-4 days using trypsin/EDTA; please note, cells grow really slow, when seeded out with lower density
Incubation:
at 37 °C with 5% CO2
Doubling time:
ca. 50-70 hours
Harvest:
cell harvest of ca. 20 x 106 cells/80 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 mutation in exon 3 of XRCC2 was verified by sequence analysis
Viruses:
PCR: EBV -, HBV -, HCV -, HIV-1 -, HIV-2 -, HTLV1/2 -, MLV -
