摘要

A non-radioisotopic, quantitative TRAP-based telom- erase activity assay was established mainly by using SYBR Green-I staining instead of radioisotope. Comparing with Conventional radioisotope based method, it was better in reproducibility and accuracy. Using this method, we found Telomerase activities were absent in normal human liver Cells, while detected in all of four human hepatoma cell Lines (BEL-7404, SMMC-7721, QGY-7903 and HCCM) without significant differences.
