Cre4/2941#6 Cell Line

This cell line is a Lig3-/- derivative of the Cre4 cell line (Cat. ESA109). Cre4 cells were stably transfected with plasmid pMA2941, which encodes Cre recombinase. As a result of Cre-mediated excision, both Lig3 alleles in Cre4/2941#6 cells are inactive, which led to the loss of mtDNA.

Cre-TM mice (JAX 004682, B6.Cg-Tg(CAG-cre/Esr1)5Amc/J) were intercrossed with Lig3LoxP mice (Nature 471(2011) 240-244) to provide tamoxifen-inducible Cre expression driven from the actin promoter. Lig3Cre-TM mouse embryonic fibroblast (MEF) cell cultures were prepared from E13.5 embryonic mesenchyme. Cells were allowed to proliferate in T-25 tissue culture flasks at 37 °C in a humidified CO2-regulated (5%) incubator and were immortalized with a retroviral construct 3315, which encodes SV40 large T antigen (J. Biol. Chem. 288 (2013) 26594-26605) and selected depending upon their ability to form colonies. One clone was selected for its superior growth characteristics and designated Cre4. These cells were further transfected with a vector 2941, which encodes G418 resistance and CMV promoter driven, myc-tagged Cre recombinase to induce a deletion in the Lig3 gene. One of the resulting clones, Cre4/2941#6 underwent a biallelic loss of the Lig3, which was accompanied by the loss of mitochondrial DNA.
