This\n requires <20% cross-reactivity to related histone PTMs determined using the SNAP-CUTANA™ K-AcylStat Panel of\n spike-in controls (EpiCypher RD193002, <strong>Figures 1 and 5</strong>). High target efficiency is\n confirmed by consistent\n genomic enrichment at varying cell inputs: 500k and 50k cells in CUT&RUN (<strong>Figures 2-3</strong>);\n 100k and 10k cells\n in CUT&Tag (<strong>Figures 6-7</strong>). High efficiency antibodies display similar peak structures\n (<strong>Figures 3 and 7</strong>) and\n highly conserved genome-wide signal (<strong>Figures 2 and 6</strong>) even at reduced cell numbers.\n H3K27ac is associated\n with gene activation and is enriched at active enhancers and promoters [1]. </p>\n </div>\n </div>\n </div>\n <div id=\"prodAccordion\">\n <div id=\"ProductDescription\" class=\"Block Panel current\">\n <h3 class=\"sub-title1\">Validation Data - CUT&RUN</h3>\n <div class=\"ProductDescriptionContainer product-droppdown__section-description-specific\">\n <section class=\"image-picker\">\n <div class=\"image-picker__left\">\n <div class=\"image-picker__main-content_active image-picker__main-content\">\n <div class=\"image-picker__header-content\">\n <button class=\"image-picker__left-arrow\">\n <svg class=\"image-picker__svg-left\" width=\"24\" height=\"24\" viewBox=\"0 0 24 24\">\n <path d=\"M16.67 0l2.83 2.829-9.339 9.175 9.339 9.167-2.83 2.829-12.17-11.996z\" />\n </svg>\n </button>\n <a href=\"/content/images/products/antibodies/13-0059_snap_specificity_cr.jpeg\" target=\"_blank\"\n class=\"image-picker__main-image-link\"><img loading=\"lazy\" alt=\"13-0059_snap_specificity_cr\"\n src=\"/content/images/products/antibodies/13-0059_snap_specificity_cr.jpeg\"\n class=\"image-picker__main-image\" />\n <span class=\"image-picker__main-image-caption\">(Click to enlarge)</span></a>\n <button class=\"image-picker__right-arrow\">\n <svg class=\"image-picker__svg-right\" width=\"24\" height=\"24\" viewBox=\"0 0 24 24\">\n <path d=\"M7.33 24l-2.83-2.829 9.339-9.175-9.339-9.167 2.83-2.829 12.17 11.996z\" />\n </svg>\n </button>\n </div>\n <p>\n <span class=\"image-picker__span-content\"><strong>Figure 1: Average SNAP specificity analysis from two\n CUT&RUN experiments</strong><br />\n CUT&RUN was performed as described in <strong>Figure 4</strong>.

Description
This H3K27ac (histone H3 acetylated at lysine 27) antibody meets EpiCypher’s lot-specific SNAP-Certified™ criteria for specificity and efficient target enrichment in both CUT&RUN and CUT&Tag applications. This requires <20% cross-reactivity to related histone PTMs determined using the SNAP-CUTANA™ K-AcylStat Panel of spike-in controls (EpiCypher RD193002, Figures 1 and 5). High target efficiency is confirmed by consistent genomic enrichment at varying cell inputs: 500k and 50k cells in CUT&RUN (Figures 2-3); 100k and 10k cells in CUT&Tag (Figures 6-7). High efficiency antibodies display similar peak structures (Figures 3 and 7) and highly conserved genome-wide signal (Figures 2 and 6) even at reduced cell numbers. H3K27ac is associated with gene activation and is enriched at active enhancers and promoters [1].
Validation Data - CUT&RUN
Figure 1: Average SNAP specificity analysis from two
CUT&RUN experiments
CUT&RUN was performed as described in Figure 4. CUT&RUN sequencing reads were
aligned to the unique DNA
barcodes corresponding to each nucleosome in the K-AcylStat panel (x-axis). Data are expressed as a
percent relative to on-target recovery (H3K27ac set to 100%). The antibody showed recovery of
H3K27ac spike-in nucleosomes as well as H3K27ac nucleosomes that contain a proximal phosphorylation
at S28 at both 500k and 50k cells. The antibody cross-reacts with extended acyl states (butyrylation
and crotonylation) at H3K27, but these are typically low abundance in cells [2].
Figure 2: CUT&RUN genome-wide
enrichment
CUT&RUN was performed as described in
Figure 4. 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 H3K27ac - 500k
cells reaction (all gene rows aligned). High, medium,
and low intensity are shown in red, yellow, and blue,
respectively. H3K4me3 positive control and H3K27ac
antibodies produced the expected enrichment pattern,
which was consistent between 500k and 50k cells and
greater than the IgG negative control.
Figure 3: H3K27ac CUT&RUN representative
browser tracks
CUT&RUN was performed as described in
Figure 4. Gene browser shots were
generated using the Integrative Genomics Viewer (IGV,
Broad Institute). H3K27ac antibody tracks display peaks at promoters and enhancers, consistent with
the biological function of this PTM. Similar results in peak structure and
location were observed for both 500k and 50k cell
inputs.
Figure 4: CUT&RUN methods
CUT&RUN was performed on 500k and 50k K562 cells with
the SNAP-CUTANA™ K-MetStat Panel (EpiCypher
19-1002) or
SNAP-CUTANA™ K-AcylStat Panel (EpiCypher
RD193002) spiked-in prior to the addition of 0.5 µg of
either IgG negative control (EpiCypher
13-0042), H3K4me3 positive control (EpiCypher
13-0041), or H3K27ac antibodies. The experiment was
performed using the CUTANA™ ChIC/CUT&RUN Kit v3
(EpiCypher
14-1048). Library preparation was performed with 5 ng of
CUT&RUN enriched DNA (or the total amount recovered if
less than 5 ng) using the CUTANA™ CUT&RUN Library Prep
Kit (EpiCypher
14-1001/14-1002). Both kit protocols were adapted for high
throughput Tecan liquid handling. Libraries were run
on an Illumina NextSeq2000 with paired-end sequencing
(2x50 bp). Sample sequencing depth was 3.8 million reads (IgG 500k cell input), 5.0 million reads
(IgG 50k cell input), 2.5 million reads (H3K4me3 500k cell input), 9.1 million reads (H3K4me3 50k
cell input), 12.6 million reads (H3K27ac 500k cell input), and 11.0 million reads (H3K27ac 50k cell
input). Data were aligned to the hg19 genome
using Bowtie2. Data were filtered to remove
duplicates, multi-aligned reads, and ENCODE DAC
Exclusion List regions.
Validation Data - CUT&Tag
Figure 5: SNAP specificity analysis in CUT&Tag
CUT&Tag was performed as described in Figure 8. CUT&Tag sequencing reads were
aligned to the unique DNA
barcodes corresponding to each nucleosome in the K-AcylStat panel (x-axis). Data are expressed as a
percent relative to on-target recovery (H3K27ac set to 100%). The antibody showed recovery of
H3K27ac spike-in nucleosomes and to a lesser extent H3K27ac nucleosomes that contain a proximal
phosphorylation at S28 at both 500k and 50k cells. The antibody cross-reacts with butyrylation at
H3K27, but this is typically low abundance in cells [2].
Figure 6: CUT&Tag genome-wide enrichment
CUT&Tag was performed as described in
Figure 8. 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 H3K27ac - 100k
nuclei reaction (all gene rows aligned). High, medium,
and low intensity are shown in red, yellow, and blue,
respectively. H3K4me3 positive control and H3K27ac
antibodies produced the expected enrichment pattern,
which was consistent between 100k and 10k nuclei and
greater than the IgG negative control.
Figure 7: H3K27ac CUT&Tag representative browser
tracks
CUT&Tag was performed as described in
Figure 8. Gene browser shots were
generated using the Integrative Genomics Viewer (IGV,
Broad Institute). H3K27ac antibody tracks display peaks at promoters and enhancers, consistent with
the biological function of this PTM. Similar results in peak structure and
location were observed for both 100k and 10k nuclei
inputs.
Figure 8: CUT&Tag methods
CUT&Tag was performed on 100k and 10k K562 nuclei with the SNAP-CUTANA™ K-MetStat Panel (EpiCypher
19-1002) or
SNAP-CUTANA™ K-AcylStat Panel (EpiCypher RD193002) spiked-in prior to the addition of 0.5 µg of
either IgG negative control (EpiCypher 13-0042), H3K4me3 positive control (EpiCypher 13-0041), or H3K27ac antibodies. The experiment was performed using the
CUTANA™ CUT&Tag Kit v1 (EpiCypher 14-1102/14-1103). Libraries were run on an Illumina NextSeq2000 with
paired-end sequencing (2x50 bp). Sample sequencing depth was 1.3 million reads (IgG 100k nuclei
input), 2.0 million reads (IgG 10k nuclei input), 3.5 million reads (H3K4me3 100k nuclei input), 8.0
million reads (H3K4me3 10k nuclei input), 8.1 million reads (H3K27ac 100k nuclei input) and 8.5
million reads (H3K27ac 10k nuclei input). Data were aligned to the hg19 genome using Bowtie2. Data
were filtered to remove
duplicates, multi-aligned reads, and ENCODE DAC Exclusion List regions.
