Label-Free Ultrasensitive Detection of Human Telomerase Activity Using Porphyrin-Functionalized Graphene and Electrochemiluminescence Technique
Using porphyrin-functionalized graphene, we construct a PCR-free, low-cost, rapid, and electrochemiluminenscence (ECL) assay for detection of telomerase activity that has been demonstrated in six different cell lines and can be used as initial screening of G-quadruplex DNA binding agents and telomerase inhibitors. This ECL sensor shows highly sensitive for detection of telomerase with the detection limit as low as 10 HeLa cells mL(-1).
