Abstract of the Invention A photoimmune method for detecting a particular polynucleotide sequence in a nucleic acid-containing sample is provided. A single-stranded polynucleotide probe substantially complementary to the polynucleotide sequence to be detected is irradiated with ultraviolet light to induce formation of UV-photoproducts, principally pyrimidine dimers. The UV-labelled probe is contacted with denatured nucleic acid from the test sample under hybridizing conditions. Duplex formation is detected with anti-UV-nucleic acid antibodies which bind the irradiated probe. The antibodies are labelled with a signalling means. A method for detecting/quantifying total DNA or RNA in a sample …
