Abstract: Droplet-based single-cell sequencing (dsc-seq) presents the ability to profile the proteome from thousands of cells simultaneously. However, the high per cell cost prevents dsc-seq workflows from being more commonly used. Hwang, et al present a method that uses splint oligonucleotides to analyze dsc-seq of DNA-barcoded antibodies from greater than 105 cells per reaction. They demonstrate that SCITO-seq produces estimates of protein expression similar to those determined via mass cytometry. Two modifications of the splint oligo design allow for extension of SCITO-seq for simultaneous profiling of surface proteins and the transcriptome of the same cell. SCITO-seq shows the possibility of use as a high-throughput method for single-cell profiling.
