library_construction_protocol: 50000 cells were resuspended in 25 µl transposase reaction mix (0.05% digitonin, 1x TD buffer, 0.08% TDE1 (Nextera DNA Library Preparation Kit, Illumina, FC-121-1031)) and incubated for 30 min, 37°C, 300 rpm. Then DNA was purified using MinElute kit (Qiagen, 28004) and eluted in 11 µl elution buffer. 1 µl was used to determine cycle number for PCR using a qPCR approach. The remaining 10 µl were complemented with 1x NEBnext High-Fidelity PCR master mix (New England BioLabs, M0541), 1.25 µM index primer 1 and 1.25 µM index primer containing a barcode. PCR was performed: 5 min 72°C, 30 sec 98°C, X cycles of 10 sec 98°C + 30 sec 63°C + 1 min 72°C, 1 min 72°C and then cleaned-up using Agencourt AMPure XP beads (Beckman Coulter, A63880).
