Droplet-based single-cell RNA sequencing of paraformaldehyde-fixed cells


 Paraformaldehyde (PFA) fixation is a common fixation technique. However, current high-throughput single-cell RNA sequencing (scRNA-seq) methods are not compatible with PFA-fixed cells. Here we introduce FD-seq (Fixed Droplet RNA Sequencing), a method for droplet-based scRNA-seq of PFA-fixed, stained and sorted cells. FD-seq offers greater flexibility for researchers, and can readily be incorporated with existing Drop-seq experimental setup.
