    • Library preparation and sequencing

      • Samples were sequenced on an Illumina NextSeq 500 sequencer, using a NextSeq 500/550 High Output Kit v2.5 (75 Cycles), 36bp PE.
    • Read mapping and Peak calling
      • Reads were mapped to the GRCm38 (mm10) mouse genome using Bowtie2 with options: --local --very-sensitive- local --no-unal --no-mixed --no-discordant.
      • Peaks were called using MACS2 with options -f BAMPE --keep-dup all –nomodel.
    Experimental Notes
    • Peaks generated using ABIN2855074 for CUT&RUN aligned well with Sox2 ChIP-seq tracks in neural stem cells (Bertolini et al., 2019).

    • The experiments were done on mouse tissue, using a small thalamic nucleus inside the brain. These are very valuable tissues composed by small numbers of cells that also express very low levels of this TF. Accordingly, the assay is particularly challenging and the success more indicative of a good antibody.

    • Sequencing depth was 0.25x coverage for the SOX2 sample and 0.15x coverage for H3K27me3, with coverage being defined as number of bases sequenced/genome size. Assuming a genome size of 2.5x109 this corresponds to 625x106 and 375x106 bases sequenced, i.e. 8.68x106 and 5.21x106 36 bp PE reads respectively.

    Background
    This intronless gene encodes a member of the SRY-related HMG-box (SOX) family of transcription factors involved in the regulation of embryonic development and in the determination of cell fate. The product of this gene is required for stem-cell maintenance in the central nervous system, and also regulates gene expression in the stomach. Mutations in this gene have been associated with optic nerve hypoplasia and with syndromic microphthalmia, a severe form of structural eye malformation. This gene lies within an intron of another gene called SOX2 overlapping transcript (SOX2OT).
