Abstract
The present invention provides methods, kits and compositions for the detection of an analyte. In the methods of the invention, a binding molecule coupled to a first polymerase is incubated with a modified polynucleotide template to form a copy of the modified polynucleotide template without any modified nucleotides. The unmodified copy is detected in a second amplification/primer extension reaction using a second polymerase that is unable to amplify the modified polynucleotide template. Detection of the unmodified copy is indicative of the presence and/or amount of the analyte in the sample. In place of the binding molecule coupled to a first polymerase, a pair of analyte-specific probes can also be used. The first analyte specific probe comprises a first binding moiety and a first portion of a first polymerase and the second analyte specific probe comprises a second binding moiety and a second portion of the first polymerase. When the binding moieties are bound to the analyte the first and second portions of the polymerase interact to form a functional polymerase complex that is used to form a copy of the modified polynucleotide template without any modified nucleotides.
