Design Notes

This part consists with promoter hEF1α and basic part rtTA3 in vector pFUGW. hEF1α is a human elongation factor 1α gene promoter and is a strong mammalian promoter. hEFα is usually used in regular expression and has a stable expressional level, which is independent with cell type. 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.
