ABSTRACT:
Nucleic acid sequences are detected by a multi-step process, involving labeling sample nucleic acid sequences, duplexing the labeled sample with a probe having a coupling element, immobilizing all of the duplexed probe and target sequence and unduplexed probe, separating specifically immobilized nucleic acid from free and non-specifically immobilized nucleic acid, releasing specifically immobilized nucleic acid, and detecting the presence of the sequence of interest by means of the label. The labeled sequence may be characterized by sizing, e.g. electrophoresis. The method provides for a sensitive and rapid means for accurate detection of sequences of interest in a wide variety of situations.
