Sequencing assay for single-droplet serum

Researchers developed an RNA sequencing assay called Small-Input Liquid Volume Extracellular RNA Sequencing (SILVER-seq) to detect circulating extracellular RNA in 5-7-microliter droplets of blood serum from liquid biopsies of participants 18-48 years of age, and demonstrated that SILVER-seq can detect tissue-specific RNA molecules, such as brain-derived RNA, and distinguish male and female biopsies as well as samples from patients with breast cancer from control samples, suggesting that with further testing SILVER-seq may prove useful in diagnostic trials based on finger-prick blood samples, according to the authors.
