简介：

Overview

This article presents a protocol for measuring relative telomere length (TL) using the monochrome multiplex quantitative polymerase chain reaction (MMqPCR) assay. The MMqPCR assay is a reliable and efficient method for assessing TL from human DNA in population-based studies.

Key Study Components

Area of Science

• Cellular aging
