The present invention provides for novel methods and compositions for nucleic acid sequence detection. Unique, identifying cleavage fragments from probes, bound to target nucleic acids, are produced during PCR by the 5′-nuclease activity of the polymerase. The identity of the targets can be determined by identifying the unique cleavage fragments.

The present invention relates to a proximity probe based detection assay (“proximity assay”) for an analyte in a sample, specifically a proximity probe extension assay (PEA), an in particular to an improvement in the method to reduce non-specific “background” signals, wherein the improvement comprises the use in such assays of a component comprising 3′ exonuclease activity, said method comprising: (a) contacting said sample with at least one set of at least first and second proximity probes, which probes each comprise an analyte-binding domain and a nucleic acid domain and can simultaneously bind to the analyte; (b) allowing the nucleic acid domains of the proximity probes to interact with each other upon binding of said proximity probes to said analyte, wherein said interaction comprises the formation of a duplex; (c) contacting said sample with a component comprising 3′ exonuclease activity; (d) extending the 3′ end of at least one nucleic acid domain of said duplex to generate an extension product, wherein the step may occur contemporaneously with or after step (c); and (e) amplifying and detecting the extension product.

Methods, compositions and kits are described for resequencing, confirming or verifying Next Generation Sequencing (NGS) results with Sanger Sequencing. These methods are particularly useful for samples having very limited quantities such as formalin-fixed, paraffin-embedded (FFPE), Laser Capture Microdissection (LCM), fine needle biopsies or aspirates.
