library_construction_protocol: Prior scChIP-seq and  scRNA-seq, PDX were digested at 37°C for 2h with a cocktail of Collagenase I (Roche, # 11088793001) and Hyaluronidase (Sigma, # H3506) as previously described (Petit et al, Lab Investigation 2013). Cells were further individualized at 37°C using a cocktail of 0.25% trypsin/Versen (ThermoFisher Scientific, #15040-033), Dispase II (Sigma, # D4693) and Dnase I (Roche, # 11284932001). Red Blood Cell lysis buffer (ThermoFisher Scientific, # 00-4333-57) was then added to degrade red blood cells. To increase the viability of the cell suspension, we removed dead cells using a Dead Cell Removal kit (Miltenyi Biotec). Cells were re-suspended in PBS/0.04% BSA (ThermoFisher Scientific, # AM2616). scRNA-seq libraries were prepared with Chromium Single cell 3' reagent v2 kit according to manufacturer's recommendations (10X Genomics).
