Comparison of adapter-dimer formation in small RNA libraries including size selection step by gel within the workflow. a Gel TBE-Urea staining showed the presence of adapter-dimer (around 120Â nt in size) in non-purified (NP) samples, and it was removed in purified (P) samples 1 and 2. b Electropherogram showed elimination of adapter-dimer (black box) from the purified exosomal cDNA library, and an increase in the small RNA library amount
