Detection of probe fragment products of basepair mismatch cleavage indicate the presence and sequence of target DNA. Detection of the target is enhanced by amplification through recycling targets by maintaining an assay temperature between the melting point of the target/probe DNA duplex and that of the target/product complex, in the presence of an amplifier comprising ammonium acetate or an amine derivative (for example, diethylamine, piperidine or ammonium carbonate). Cleavage reduces the size of the duplex, and thus lowering its melting point. The amplifier releases the target from the complex, thereby permitting further catalysis of cleavage and effectively amplifying the signal to be detected.
