Electropherograms obtained for DNA fragment analysis by capillary electrophoresis to analyze adapter-dimer formation. Three different cDNA libraries from urinary exosomal samples showed the presence of adapter-dimer (black box), high amount of adapter-dimer with high cDNA library (grey box) (a), low amount of adapter-dimer with low cDNA library (b), and high amount of adapter-dimer with low cDNA library (c)
