Cell fixation and preservation for droplet-based single-cell transcriptomics.

“For rehydration, cells were either kept on ice after fixation (Fixed) or moved from –80 °C to 4 °C (Fixed 1 or 3 weeks) and kept in the cold throughout the procedure. Cells were pelleted at 1000 to 3000 × g, resuspended in PBS + 0.01% BSA, centrifuged again, resuspended in PBS + 0.01% BSA, passed through a 40- or 35-μm cell strainer, counted and diluted for Drop-seq in PBS + 0.01% BSA as described above.”
