Tet systems—legacy products

For more than two decades, Tet-On and Tet-Off systems have been the highest-performing and most-cited inducible expression systems for mammalian cells. During this time, a series of improvements to the systems have resulted in three distinct generations of the technology.

For more than two decades, Tet-On and Tet-Off systems have been the highest-performing and most-cited inducible expression systems for mammalian cells. During this time, a series of improvements to the systems have resulted in three distinct generations of the technology. The most recent and highest-performing generations of the tetracycline-inducible expression system are Tet-One and Tet-On 3G technologies (details are found in other areas of our website). Below are links to older first- and second-generation Tet system products.
