| Abstract: | To construct a single tetracycline-regulatable plasmid vector based on the double tetracycline-regulatable plasmid vector system for regulating HSV-tk gene expression so as to effectively kill HeLa cells. Two tetracycline operator(TetO2) was cloned into pcDNA3.1 and a cassette was made for a cytomegalovirus-type 2 tetracycline operator(CMV-TetO2) promoter, and the obtained vector was named pcDNA3.1-CMV-TetO2. Herpes simplex virus thymidine kinase(HSV-tk) gene and tetracycline repressor(TR) gene were cloned ... |
