基本信息
Cell Line Origin【细胞系来源】 | Human (HeLa) with tTA |
Cell Line Description【细胞系描述】 | 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 |
Application【应用】 | Specific and stringent control of the activity of an individual gene (luciferase) in a mammalian cell can be monitored. It is also suitable for creation of |
Culture Medium【培养基】 | EMEM (EBSS) + 2mM Glutamine + 1% Non Essential Amino Acids (NEAA) + 1% Vitamins + 500μg/ml G418 + 300μg/ml Hygromycin + 10% Foetal Bovine Serum (FBS). Freeze cells in 40% medium, 10% Dimethyl Sulphoxide (DMSO) and 50% Foetal Bovine Serum (FBS). |
Subculture Routine【传代培养常规】 | Split sub-confluent cultures (70-80%) 1:5 to 1:20 i.e. seeding at 5x1,000 to 2x10,000 cells/cm2 using 0.25% trypsin or trypsin/EDTA. Alternatively cells can be washed with PBS and subcultured after addition of PBS with 0.8mM EDTA (30% of original volume) |
