Methods and/or Use of Oligonucleotide Conjugates for Suppressing Background Due to Cross-Hybridization

The present disclosure is directed to methods and/or uses of oligonucleotide conjugates for assays and detections and related systems and/or kits for suppressing background due to cross-hybridization. Certain methods are directed to a method for detecting one or more biological targets of a sample in a detection assay, comprising: providing a molecular probe, comprising a binding moiety and an oligonucleotide sequence, to a sample comprising one or more biological targets; binding the one or more biological targets with the binding moiety; providing a detectable component to the sample, wherein the detectable component comprises a signal generating moiety conjugated to an oligonucleotide sequence complementary to the oligonucleotide sequence of the molecular probe; hydridizing the oligonucleotide sequence of the target-bound molecular probe to the detectable component; and detecting a signal generated from the hydridized detectable component. Various other embodiments, applications etc. are disclosed herein.
