TetR HEK293 Cell Line
The TetR HEK293 Cell Line is a HEK293 cell line expressing the repressor of the tetracycline resistance element (TetR), creating an inducible system based on the presence of Tetracycline or Doxycycline in the cell culture media. These cells can be transfected with a target of interest under the control of a strong promoter and the Tetracycline Operon. In the absence of tetracycline or doxycycline, TetR binds to the operon and represses transcription. When exposed to tetracycline or doxycycline, TetR loses affinity for the tetracycline resistance element expression of the target of interest occurs.
This cell line has been validated by stimulation with doxycycline.

TetR, or Tet repressor proteins play a role in development of antibiotic resistance to tetracycline (Tc). Tc are a family of antibiotics that kills bacteria by interfering with protein synthesis. Resistance to Tc occurs by expression of Tc resistance genes, which are regulated by TetR. In addition to the study of mechanisms of antibiotic resistance, the use of TetR has been used as a mode to regulate promoter expression, and thus create inducible cell models. These inducible cell models have been crucial for the understanding of cellular pathways.
