The hTERT activity of CCRC-1 cells. A TRAPeze XL Telomerase Detection Kit was used to detect the hTERT activity of CCRC-1 cells at passage 10, 15, 20, 25 and 30. A549 human lung cancer cells were used as positive control. The hTERT activities are expressed as Total Product Generated (TPG). Data are represented as the mean ± SD of three independent experiments. (***P < 0.001, compared with A549).
