Analysis of the exosomal miRNA levels by quantitative RT-PCR.
RNA was isolated with Total Exosome RNA and Protein Isolation kit from serum exosomes recovered with Total Exosome Isolation (from serum) reagent, and an ultracentrifugation protocol. MicroRNAs hsa-let7e and hsa-miR26a levels were quantified by qRT-PCR using TaqMan assays.
