Figure 1. Induction with Tet-Dual simultaneously produces two proteins from a bicistronic mRNA.


Figure 2. Tet-Dual System vectors. The Tet-Dual transactivator expression vectors constitutively express either Tet-On Advanced or Tet-Off Advanced, and the fluorescent protein, ZsGreen1 (Panel A). pTRE-Dual2 is a Tet-regulated inducible expression vector that coexpresses mCherry and a second gene that is cloned in the multiple cloning site (MCS) (Panel B). pTRE-Dual1 coexpresses two user-defined genes.
