HRP-mimicking DNAzyme activity is controlled by an aptamer that stems with part of the active site in absence of the ligand. In presence of the ligand the inhibiting stem is destabled and thus the HRP-mimicking DNAzyme's activity is recovered.

On the Southern Blot

Not only can the HRP be used in the ApatBody but the part can be adapted in other systems as well. We could show that the HRP-mimicking DNAzyme can be blotted in a Southern blot and its activity is recovered on the membrane. Thus the HRP-mimicking DNAzyme can be used as an easy and fast readout on a Southern blot. It can be connected to any RNA or DNA via splinted ligationKershaw2012 (Fig. 4). This system can be used to avoid working with radioactive isotopes and also poses an alternative to using fluorescent probes.

Figure 5. Switchable HRP DNAzyme for software validation

HRP-mimicking DNAzyme activity is controlled by an aptamer that stems with part of the active site in absence of the ligand. In presence of the ligand the inhibiting stem is destabled and thus the HRP-mimicking DNAzyme's activity is recovered.
