Mice were sacrificed 3 or 15 days after rAAV injection and liver tissue was flash-frozen in aliquots. Liver tissue (~100 mg) was homogenized in RINO 1.5-ml Screw-Cap tubes filled with stainless steel beads and 1mL of NE buffer using a bead homogenizer (Next Advance Bullet Blender Storm - BBY24M) at speed 8 for 4 minutes. The homogenate was transferred into to a 50mL tube with 12mL of NE buffer and incubated on ice for 10 min. Nuclei were pelleted by a 5 min centrifugation at 600g, the supernatant was decanted, and the pellet was resuspended in 1mL of NE buffer. Nuclei were quantitated after Trypan Blue staining using an automated cell counter (Countess, Thermo Fisher) and diluted accordingly. 5e5 nuclei per sample was used for Tn5 library preparation Total gDNA was extracted using a QIAamp DNA Mini kit (Qiagen) including RNAse treatment. The protocol for Illumina DNA prep was followed as per manufacturer's instructions with 100ng of DNA as input, 30min tagmentation and 8 cycles of PCR. The same indexed primers as for Cut&Tag were used for PCR amplification. Illumina DNA prep kit. Sequencing was performed with Illumina NovaSeq 6000, 150 cycles total per lane (2 lanes total), 2x75 paired-end reads, depth of >15M reads per sample.
