Figure 1: SNAP specificity analysis in CUT&RUN

CUT&RUN was performed as described above. CUT&RUN sequencing reads were aligned to the unique DNA barcodes corresponding to each nucleosome in the K-MetStat panel (x-axis). Data are expressed as a percent relative to on-target recovery (H3K4me2 set to 100%).

Figure 2: CUT&RUN genome wide enrichment

CUT&RUN was performed as described above. Sequence reads were aligned to 18,793 annotated transcription start sites (TSSs ± 2 kbp). Signal enrichment was sorted from highest to lowest (top to bottom) relative to the H3K4me2 - 50k cells sample (all gene rows aligned). High, medium, and low intensity are shown in red, yellow, and blue, respectively. H3K4me2 antibody produced the expected TSS enrichment pattern, which was consistent between 500k and 50k cells and greater than the IgG negative control.

Figure 3: H3K4me2 CUT&RUN representative browser tracks

CUT&RUN was performed as described above. Gene browser shots were generated using the Integrative Genomics Viewer (IGV, Broad Institute). Similar results in peak structure and location were observed for both cell inputs.

Figure 4: Antibody efficiency analysis in CUT&RUN using cell input correlation

CUT&RUN was performed as described above. Genome-wide correlation analysis was performed to compare H3K4me2 antibody enrichment using 500k cell and 50k cell inputs. The log of the number of reads per 75 bp binned region across the genome is plotted for both samples. CUT&RUN data generated using this H3K4me2 antibody are highly correlated between the two cell inputs (Pearson correlation r = 0.942), indicating high efficiency of H3K4me2 antibody target recovery.
