Inducible protein stabilization systems—product selection guide

The ProteoTuner systems use a powerful, unique technology to regulate the quantity of your protein of interest, at the post-translational level. ProteoTuner technology has been successfully used with cytosolic and membrane-bound proteins in a variety of cell types, organisms, and animal models.

ApplicationRecommended systemsComments
For easy-to-transfect cells
N-terminal DD tag ProteoTuner Shield System N
ProteoTuner Shield System N (w/ AcGFP1)
Most of the proteins that Takara Bio has tested show a better destabilization profile when the DD tag is fused to the N-terminus of the protein of interest. Available with or without a built-in green fluorescent protein transfection control.
C-terminal DD tag ProteoTuner Shield System C A specific DD tag mutant for C-terminal tagging; provides a slightly reduced destabilization activity in the absence of Shield1.
For difficult-to-transfect, dividing or nondividing cells
N-terminal DD tag Lenti-X ProteoTuner Shield System N
Lenti-X ProteoTuner Shield System N (w/ ZsGreen1)
Most of the proteins that Takara Bio has tested show a better destabilization profile when the DD tag is fused to the N-terminus of the protein of interest. Available with or without a built-in green fluorescent protein transfection control.
C-terminal DD tag Lenti-X ProteoTuner Shield System C A specific DD tag mutant for C-terminal tagging; provides slightly reduced destabilization activity in the absence of Shield1.
For difficult-to-transfect, dividing cells
N-terminal DD tag Retro-X ProteoTuner Shield System N
Retro-X ProteoTuner Shield System N (w/ZsGreen1)
Most of the proteins that Takara Bio has tested show a better destabilization profile when the DD tag is fused to the N-terminus of the protein of interest. Available with or without a built-in green fluorescent protein transfection control.
Shield1 ligand
Controlling DD activity Shield1 Membrane-permeable small molecule; binds specifically to the DD tag, to inactivate protein degradation.
