ProteoTuner plasmid expression systems allow for rapidly regulating the presence or absence of a protein of interest in your target cells. Clone your gene of interest in-frame with the destabilization domain tag (DD), either at the N or C terminus. In the absence of the Shield1 ligand in the culture medium, the DD-tagged fusion protein is immediately destabilized, but when Shield1 is added, the protein accumulates to detectable levels within 15–20 minutes.

Upon Shield1 removal, the halftime for the fusion protein`s degradation can be as short as 30 minutes. Lentiviral and retroviral formats are also available.
