A TRAP assay on human colonic tumor telomerase activity is reported. The reliable result is obtained when 1.8 mmol/L Mg2+ and 55℃ annealing temperature are adopted. The other two factors affecting reliability are quantity of the extract and contamination of the positive DNA fragments in the reaction.
