摘要：

Telomere shortening is tin important risk factor for cancer and accelerated aging, Here we describe the development of a simple and reproducible method to measure absolute telomere length. Based on Cawthon's quantitative real-time PCR (qRT-PCR) assay, our method uses an oligomer standard that can be used to generate absolute telomere length values rather than relative quantification. Me demonstrate a strong correlation between this improved method and the "gold standard" of telomere length measurement-terminal restriction fragment analysis (TRF) by, Southern hybridization. The capability to generate absolute telomere length values should allow a more direct comparison of results between experiments within and between laboratories.
