Intercalated samples were washed with once with CSM and twice with
double distilled water, and then re-suspended in a solution of normalization
beads (Fluidigm). Samples were filtered prior to mass cytometry analysis through
a 35-µm membrane and analyzed at a flow rate of approximately 500
cells/sec. Samples were normalized and de-barcoded as described previously
(15 (link),16 (link)).
