Abstract:
The present study describes an empirically discovered phenomenon that might be useful for development of a sensitive and rapid methodology for quantification of telomerase activity assay with simple data acquisition and possibility for calculation of telomerase product in absolute units. The method is based on the design and application of two single-stranded telomere sensing probes consisting of dual-labeled 16-mer oligonucleotides (fluorescent Cy3/Cy3-labeled and non-fluorescent IowaBlack/BHQ-labeled) that can simultaneously hybridize on the primary product of the telomerase reaction.

Labeling DNA Probes
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...
