Blood extracellular vesicle long RNA sequencing of human blood from pancreatic ductal adenocarcinoma (PDAC), chronic pancreatitis (CP) and healthy individuals
Blood samples were collected from all participants in 10-mL EDTA-coated Vacutainer tubes. Plasma was separated by centrifugation at 3,000 rpm for 10 min at room temperature (25°C) within 2 h after blood collection and then centrifuged at 13,000 rpm for 10 min at 4°C to remove debris. Isolated plasma samples were stored at -80°C until use. EV RNA were isolated by affinity-based binding to spin columns using an exoRNeasy Serum/Plasma kit (Qiagen, Hilden, Germany). RNA libraries were prepared for sequencing using SMARTer® Stranded Total RNA-Seq Kit - Pico Input Mammalian. RNA-seq was performed  by the Illumina sequencing platform on a 150-bp paired-end run. Overall design: Blood extracellular vesicle long RNA profiles of human plasma by deep sequencing using Illumina Hiseq.
