Abstract
Telomerase activity in cancer cells is commonly analyzed by a polymerase chain reaction (PCR)-based assay termed the telomeric repeat amplification protocol (TRAP). However, nonspecific inhibition of Taq polymerase during the PCR step is frequently observed in inhibitor analysis or drug screening. Thus, the removal of excess inhibitors prior to PCR is an essential step for the proper evaluation of telomerase inhibitory effects. Here, a size exclusion spin column was applied to remove small molecular weight inhibitors from the telomerase extension products. The spin column-added protocol, termed sTRAP, provides a more reliable estimation of the inhibitory effects of telomerase activity. ? 2015 Elsevier Inc. All rights reserved.
