Disclosed are compositions and methods for nucleic acid amplification reactions that reduce, prevent, or eliminate artifacts; increase efficiency; increase specificity; and/or increase consistency. The disclosed method can combine, for example, the use of open circle probes that can form intramolecular stem structures; the use of matched open circle probe sets in the same amplification reaction; the use of detection primers and detection during the amplification reaction; the use of a plurality of detection rolling circle replication primer, a secondary DNA strand displacement primer and a common rolling circle replication primer in the same amplification reaction; and/or the use of peptide nucleic acid quenchers associated with detection rolling circle replication primers. Such combinations can produce, in the same amplification reaction, the benefits of each of the combined components.
