U2OS-LacO-I-SceI-TetO Cell Line細(xì)胞株

U2OS bone osteocarcinoma cell line integrated with I-Scel endonuclease site in-between a lac operator (lacO) sequence and a tet operator (TetO) sequence. This allows for a Lac-repressor/operator-tethering system designed to probe the role of chromatin condensation in DNA damage response (DDR).

Highlights:

Consists of 10 kb tandem arays of the Lac operator (lacO) sequence adjacent to an I-SceI endonuclease site stably integrated into human U2OS cells at two different chromosomal locationsDefined chromatin domains can be generated by virtue of tethering fusion proteins between chromatin modifiers and the Lac repressor (LacR) protein, which binds with high affinity to the lacO regions
DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. U2OS is an established human epithelial cell line isolated back in the 1960s from a 15 year old female suffering from bone cancer or osteosarcoma. The cells came from a moderately differentiated sarcoma on the tibia and allow for fast growth and have been shown to have high transfection efficiencies.
