Abstract

Disclosed are compositions and methods useful for labeling and detection of analytes. The compositions generally are associations of three components: reporter binding agents, amplification target circles, and DNA polymerase. The compositions are assembled prior to their use in a rolling circle amplification reaction and can be stored and transported prior to use without substantial loss of activity. The reporter binding agents generally are composed of a specific binding molecule and a rolling circle replication primer. The specific binding molecule can be specific for a target molecule. The rolling circle replication primer has sequence complementary to the amplification target circle. The DNA polymerase can interact with the rolling circle replication primer and amplification target circle. For use as a general reagent, the specific binding molecule is not bound to the target molecule until the composition is used in an assay.
