Abstract
Telomere measurement by quantitative PCR amplification is a well-known simple method to detect telomere length that involves large numbers of samples. The method has been developed by Cawthon in 2002 (Cawthon, Nucleic Acids Res 30:47e–47, 2002) and remains the most frequently used technique either in original or modified version. Telomere length is estimated by comparing the amount of telomere repeat amplification product (T) to a single copy gene (S) product. The T/S ratio correlates with the average telomere length. Cawthon suggested and recommended the use of 36B4 (RPLP0) as a single copy gene. However, Cawthon’s suggestion was no longer considered a single copy gene and the gene was not suitable and appropriate for normalization.
We thereby introduced a simple method for relative measurement of average human telomere length using quantitative real-time PCR. Our protocol was based on Cawthon’s initial technique (Cawthon, Nucleic Acids Res 30:47e–47, 2002), modified by single-copy gene (SCG) primers and optimized.
This technique is rapid, low cost, not demanding on DNA amount (or live cells), and can be used for a high-throughput screening and time monitoring.
