Parse scRNA Sequencing

Parse scRNAseq (single-cell RNAseq using fixed cells)

Parse scRNAseq uses Evercode™ split-pool combinatorial, which revolutionizes the way large-scale single-cell RNA sequencing experiments are conducted. The technology was based on 2018 Science paper SPLIT-seq. Cells are first fixed and permeabilized, turning them into their own reaction vessels, removing the need to capture individual cells in droplets or microwells. Then, in-situ combinatorial barcoding steps take place to create libraries ready for sequencing. The fixation protocol is able to store the samples and run them all together to reduce batch effect and give more flexibility.

Details of the final whole transcriptome sequencing library structure are below:
