Figure 5. . Correlation of telomere length measured by monochrome multiplex quantitative polymerase chain reaction with Southern blot.

The scatter diagram comparing relative telomere length (telomeric DNA with fluorescent signals/single-copy housekeeping gene ratios) measured by monochrome multiplex quantitative polymerase chain reaction and absolute telomere length (kilobyte) measured by Southern blot analysis in leukocytes from 94 participants. A strong correlation was observed between both methods (r = +0.896).
