- A mannitol-based buffer improves single-cell RNA sequencing of high-salt marine cells. Scully, Tal D Klein, Allon M Animals Single-Cell Analysis Mannitol Sequence Analysis, RNA Buffers Ciona intestinalis Salinity Gene Expression Profiling RNA-Seq Transcriptome Single-cell RNA sequencing (scRNA-seq) enables discovery of novel cell states by transcriptomic profiling with minimal prior knowledge, making it useful for studying non-model organisms. For most marine organisms, however, cells are viable at a higher salinity than is compatible with scRNA-seq, impacting data quality and cell representation. We show that a low-salinity phosphate buffer supplemented with D-mannitol (PBS-M) enables higher-quality scRNA-seq of blood cells from the tunicate Ciona robusta. Using PBS-M reduces cell death and ambient mRNA, revealing cell states not otherwise detected. We additionally validate PBS-M in a second tunicate species. This simple protocol modification could enable or improve scRNA-seq for many marine organisms.
