NIH 3T3 Duo Cell Line

The NIH 3T3 Duo Cell Line allows for the direct study of the dynamics of single double-strand breaks (DSBs) and translocations in living mammalian cells in vivo.

NIH3T3 cells which contain integrated into chromosome 7 the ISceI restriction endonuclease site adjacent to an array of the Lac-operator DNA sequence (LacO, 256 copies) and three integrations on chromosomes 1 and 10 (integrations on two chromosome homologs) of the TetO-ISceI-TetO array (TetO, 96 copies). This cell line also coexpresses the fluorescent repressors LacR-GFP and TetR-mCherry.

We culture the cells in the presence of IPTG and Doxycycline to prevent the binding of the repressors to the respective operators. In order to visualize the arrays wash IPTG and Doxycycline as explained in the protocol (Roukos et al., Nat Protoc. 2014). We routinely culture the cells in the absence of the drugs for selection and when necessary we resort the cells by FACS for the wished LacRGFP/TetRmCherry expression levels.
