Figure 3 From: The three-dimensional organization of telomeres in the nucleus of mammalian cells Demonstration of the signal-to-noise and spatial resolution of our measurements. The fluorescence intensity is bright (typical signal-to-noise ratio of 10:1). Two pairs of telomeres are shown, 1200 nm apart (top), which can be easily separated, and 400 nm apart (bottom). The inserts show the actual images.Back to article page
