Snap-frozen normal human brain tissue was obtained by 10x Genomics from Avaden BioSciences. Nuclei were isolated following the Nuclei Isolation from Complex Tissues for Single Cell Multiome ATAC + Gene Expression Sequencing Demonstrated Protocol (CG000375, Rev D). Paired ATAC and Gene Expression libraries were generated as described in the Chromium GEM-X Epi Multiome User Guide (CG001689, Rev B) and sequenced on an Illumina NovaSeqX+ with approximately 80,000 ATAC read pairs per cell and 50,000 GEX read pairs per cell.
