Probe hybridization is a molecular biology technique that detects a specific DNA or RNA sequence by allowing a labeled single-stranded nucleic acid probe to bind, or hybridize, to its complementary target sequence. Hybridization relies on the base-pairing rules of nucleic acids, so a probe designed to match a sequence of interest will anneal selectively to that sequence within a complex mixture. The probe carries a detectable label, such as a fluorescent dye, an enzyme, or a radioactive or chemical tag, which reveals where and whether the target is present. This principle underlies many widely used methods, including Southern and northern blotting, fluorescence in situ hybridization, microarrays, and various diagnostic and detection assays. Probe hybridization is valued for its specificity and sensitivity, enabling researchers to confirm the presence of a gene, measure transcript abundance, locate sequences on chromosomes, or identify pathogens. The reliability of results depends on probe design, hybridization conditions, and stringency controls that distinguish true matches from non-specific binding. As a foundational tool in genetics, diagnostics, and gene-expression analysis, probe hybridization remains central to nucleic acid research.
