摘要

The Telomeric Repeat Amplification Protocol (TRAP) and its modified versions (including ours, TP-TRAP) change the size and/or the ratio of the telomerase products in the amplification stage of the assay. Based on our recently published method we developed a new TRAP. This method ensures that the number of telomeric repeats present in the original telomerase products does not change on PCR amplification. The usefulness of the method was proved with amplification of chemically synthesized telomerase products and a newly designed telomerase substrate oligonucleotide. This is the first report in which the PCR products directly reflect the size distribution of telomerase products generated by the enzyme.
