A system was devised that enables quantitative, ligand-dependent exponential amplification for various ligands that can be recognized by an RNA aptamer. The aptamer is linked to an RNA enzyme that catalyzes the joining of two oligonucleotide substrates. The product of this reaction is another RNA enzyme that undergoes self-sustained replication at constant temperature, increasing in copy number exponentially. The concentration of the ligand determines the amount of time required for the replicat ...[more]
