Abstract:
We report the sensitive detection of telomerase activity by using exonuclease III-aided target recycling to amplify the signal produced by a chimeric LNA-DNA molecular beacon. We demonstrate the specific detection of as few as 30 telomerase-positive breast cancer cells in a single-measurement fluorescence assay that avoids the problematic PCR and gel analysis of the current "gold-standard" assay.
