Opis

Pochodzenie linii komórkowej

Human (HeLa) with tTA

Opis linii komórkowej

X1/5 is a HeLa cell line stably transfected with a tet repressor fused with the activating domain of virion protein 16 of herpes simplex virus thus generating a tetracycline-controlled transactivator (tTA) This stimulates transcription from a minimal promoter sequence derived from the human cytomegalovirus promoter IE combined with tet operator sequences. Integration of a luciferase gene controlled by a tTA-dependent promoter into this tTA producing HeLa cell line leads to high levels of tetracycline-sensitive luciferase expression. The luciferase activity can be regulated over up to five orders of magnitude depending on the concentration of tetracycline in the culture medium (0-1ug/ml). Specific and stringent control of the activity of an individual gene (luciferase) in the mammalian cell can be monitored. It is also suitable for creation of on/off situations and analysis of mRNA decay rates under physiological conditions
