Characterization of exosomal RNA (esRNA) extracted from purified nanovesicles from fresh human aqueous humor. The esRNA was evaluated using Agilent Bioanalyzer 2100 with Agilent RNA 6000 Pico Kit. A) Shows the RNA ladder and B) displays extracted esRNA from one of the human aqueous humor samples. The size of extracted esRNA was less than 200 nucleotides (nt), mostly around 25 nt. C) shows the miRNAs that were identified via small RNA sequencing using Illumina MiSeq sequencing system. The height of each bar indicated the number of sequence reads with perfect match to mature miRNA.
