This protocol outlines how to isolate, wash, and count nuclei suspensions for use with the Chromium Next GEM Single Cell Multiome ATAC + Gene Expression (GEX) protocol (CG000338). Cryopreserved primary cells (PBMCs) and cell lines (GM12878 cells; 3T3 cells) were used to develop this protocol. PBMCs were cryopreserved in IMDM + 40% FBS + 15% DMSO. Cell lines were cryopreserved in RPMI + 15% FBS + 5% DMSO. Optimization of some protocol steps (e.g. lysis time, centrifugation speed/time and filtration steps) may be needed based on cell type.

Caution: RNAse rich samples may need additional optimization. Please see: Can I use RNase-rich tissue samples for single-cell gene expression or Multiome assays?

This protocol is only compatible with the Chromium Single Cell Multiome ATAC + Gene Expression reagent kits. Do not use with standalone Single Cell ATAC or SC3'v3.1 assays.
