pCMV-rtTA3
Usage and Biology
This part consist with promoter pCMV and basic part rtTA3 in the vector pcDNA3.1. pCMV is a strong mammalian expression promoter derived from human cytomegalovirus, usually used for routine expression, with high expression levels but may be inhibited in some cells. rtTA is a key component of Tet-On system, and rtTA3 is third generation rtTA. rtTA3 is an activation factor of pTRE. rtTA3 isn’t active when it is present alone, and it can be active when combine with doxycycline (DOX), then the complex can combine to pTRE and start the downstream transcription. When DOX get removed the rtTA3 will became no activation again.
In our experiment, pCMV-rtTA3 is used to test the effect of the influence of different promoter to the expression of rtTA3.
This result shows the influence of two kinds of promoter pCMV and hEF1α to the expression.
