Disclosed is a method and materials for amplifying nucleic acid sequences by limited primer extension. The disclosed method involves association of a primer with a template, extension of the primer for a short distance, termination of extension, and dissociation of the primer from the template, whereupon the events repeat with a new primer. The repeated association, extension, and dissociation of primers from a single template sequence results in amplification of the extended sequences. The termination of extension can be effected by a feature of the template sequence. The reaction can be carried under a single set of conditions, such as isothermal conditions, based on the thermodynamics of dissociation of the extended primers. The disclosed method is particularly suited to detection of nucleic acid sequences. Multiple sequences can be amplified and detected in the same reaction by targeting multiple sequences with extension primers. |
