Abstract
Methods for diagnosis employing polynucleotides having oligonucleotide sequences substantially homologous to a sequence of interest, where the presence or absence of hybridization at a predetermined stringency provides for the release of a label from a support. Particularly, various techniques are employed for binding a label to a support, whereupon cleavage of either a single or double strand, a label may be released from a support, where the release of the label can be detected as indicative of the presence of a particular oligonucleotide sequence in a sample. The method finds use in diagnosis of disease, genetic monitoring, and analyzing nucleic acid mixtures.
