Abstract
We designed a method termed Telospot to discover and characterize telomerase modulators as anticancer drugs or chemical biology tools. Telospot is based on a highly efficient human telomerase expression system and the detection of telomerase DNA reaction products in macroarray format. Telospot offers a highly scalable, cost- and time-effective alternative to presently available telomerase assays, which are limited by the requirement for PCR, telomerase purification or technologies not amenable to high throughput.
