Dissociated Lats1/2-deficient mouse tumor cells (∼50,000 cells) were spun down at 500 x g for 5 min at 4C, lysed in cold Lysis buffer (10 mM Tris-HCl, pH 7.4, 10 mM NaCl, 3 mM MgCl2, 0.1% IGEPAL CA-630). Afterspinning down at 500 x g for 10 min at 4C, nuclei were resuspended in transposition mix containing 25 μl TD (2x reaction buffer) 2.5 μl TDE1 (Nextera Tn5 Transposase), 22.5 μl Nuclease Free H2O, at 37°C for 30 min. Immediately following transposition, DNA were purified using a Qiagen MinElute PCR Purification Kit. Transposed DNA fragments were subsequently amplified and the amplified library was purified using Qiagen MinElute PCR Purification Kit. Libraries were generated using the Ad1_noMX and Ad2.1–2.4 barcoded primers and were amplified for 7–9 total cycles. Libraries were purified with AMPure beads (Agencourt) to remove contaminating primer dimers. All libraries were sequenced on the Illumina HiSeq 2000.
