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. This system can be used to avoid working with radioactive isotopes and also poses an alternative to using fluorescent probes.
