Single-cell/nucleus sequencing has been increasingly used to study specific cell populations. However, cells/nuclei often become diluted during isolation steps and are difficult to reconcentrate through centrifugation. Here, we present a protocol for sample enrichment using concanavalin A-conjugated magnetic beads. We describe steps for dissection, nuclei isolation, and fluorescence-activated cell sorting (FACS). We then detail procedures for nuclei enrichment and library preparation. This protocol enables efficient retrieval and enrichment of cells/nuclei following FACS and integrates into existing workflows of various 10× Genomics applications.
