Abstract
A method for detecting a target nucleic acid molecule is provided, comprising the steps of (a) reacting a mixture comprising (i) a target nucleic acid molecule; (ii) a single-stranded nucleic acid probe containing a scissile linkage; (iii) an enzyme capable of cleaving the probe portion of a double-stranded target-probe complex at the scissile linkage; and (iv) ribosomal protein and/or spermine, under conditions and for a time sufficient to allow the target nucleic acid and probe to hybridize to each other and form a double-stranded target-probe complex, followed by cleavage of the probe and cycling of the target to a new uncleaved probe, such that one or more portions of the cleaved nucleic acid probe are released from the target-probe complex; and (b) determining whether cleaved portions of the nucleic acid probe are produced, and thereby detecting the presence of the target nucleic acid.
