Demonstrated Protocol, For use with cell lines and PBMCs, Last Modified on July 8, 2019, Permalink
This protocol outlines how to isolate, wash, and count nuclei suspensions for use with the Chromium Single Cell ATAC protocol. Cryopreserved primary cells (PBMCs) and cell lines (GM12878 cells; EL4 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.
