Although combiSingle-cell and ultra-low-input RNA-Seq are powerful tools for studying the transcriptome in an unbiased manner from minimal input. 1 A,B; see Methods). In these cases, UMIs (Unique Molecular Identifiers) should be used to prevent the removal of natural duplicates. However, pre-amplification-based and molecule index-based library construction methods boost bias or require higher throughput. In this study, we microscopically isolated murine nodose and jugular capsaicin-sensitive / Trpv1-expressing C-fiber neurons and performed transcriptome profiling using ultra-low input RNA. For low input RNA-seq, Im-cpl with 50, 20, 10 ng input and Sol-RT with 100 ng input were repeated twice.
