Telomerase is a potential cancer marker. We developed a new and robust telomerase activity assay which combines the modified telomere repeat amplification protocol (TRAP) with magnetic beads-based electrochemiluminescence (ECL) detection. The high performance of this assay is related to the determination of telomerase activity from single cell levels, and ECL intensity is linear over the range of 1-1000 HeLa cell equivalents. The proposed telomerase assay offers a highly cost- and time-effective alternative to presently available telomerase assays, which are limited by tedious and complicated post-PCR detection.
