Abstract
The invention provides compositions and methods for the detection of targets in a sample; in particular, an immunohistochemistry (IHC) sample. Probes and detectable labels may be provided in multiple layers in order to increase the flexibility of a detection system, and to allow for amplification to enhance the signal from a target. The layers may be created by incorporating probes and detectable labels into larger molecular units that interact through nucleic acids base-pairing, including peptide-nucleic acid (PNA) base-pairing. Optional non-natural bases allow for degenerate base pairing schemes. The compositions and methods are compatible with immunohistochemistry (IHC), but also could be used in immunocytochemistry (ICC), in situ hybridization (ISH), flow cytometry, enzyme immuno-assays (EIA), enzyme linked immuno-assays (ELISA), blotting methods (e.g. Western, Southern, and Northern), labeling inside electrophoresis systems or on surfaces or arrays, and precipitation, among other general detection assay formats. The invention is also compatible with many different types of targets, probes, and detectable labels.
