Methods for the detection of biologically relevant interactions by highly precise catalytic control elements based on hairpin ribozymes, and their subsequent analysis are described. These include ribozyme design, catalytic performance in real time as a function of fluorescence signal amplification, and applications for sensing protein and nucleic acid interactions in high-throughput formats. Detailed instructions for two of our main reporter ribozyme formats that either follow repressible or inducible regulatory mechanisms are provided. We have shown that these techniques can be applied for detecting diverse target molecules including microRNAs, or protein-protein interactions. These reporter systems thus represent a general way to obtain signal-amplifying sensors for diverse applications in molecular profiling.
