H3.3 is enriched in\n promoters and enhancers of active genes as well as transcriptionally inactive heterochromatin, reflecting\n the diverse functions of this unique histone variant [1]. The antibody is highly specific for H3.3 without\n cross-reacting with canonical H3.1. Binding is not impacted by methylation or mutations at amino acids\n H3.3K27 or H3.3K36 (<strong>Figure 1</strong>).\n </p>\n <p>\n H3.3 differs from canonical H3.1 at just five amino acids (31, 87, 89, 90, 96). Most of these changes are\n located in the inaccessible histone core, making them unfit epitopes for chromatin mapping experiments. The\n SNAP-Certified™ H3.3 antibody specifically interacts with amino acid 31, where a serine is substituted for\n alanine, allowing clear distinction between H3.3 and H3.1 in chromatin mapping experiments.\n </p>\n <p>\n The H3.3 antibody meets EpiCypher’s SNAP-Certified™ criteria for specificity and efficiency in CUT&RUN. This\n requires <20% cross-reactivity to other histone variants, determined using SNAP-CUTANA™ Spike-in Controls\n (<strong>Figure 2</strong>). High target efficiency is confirmed by consistent genomic enrichment at 500k\n and 50k cells\n (<strong>Figure 3</strong>).\n </p>\n <p>\n <em>Note: This antibody is sensitive to dithiothreitol (DTT).</em>\n </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/13-0061-luminex-multiplexed-specificity.jpeg\"\n target=\"_blank\" class=\"image-picker__main-image-link\"><img loading=\"lazy\"\n alt=\"13-0061-luminex-multiplexed-specificity\"\n src=\"/content/images/products/antibodies/13-0061-luminex-multiplexed-specificity.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: Luminex multiplexed specificity\n profiling</strong><br />\n Histone H3.3 antibody was assessed using a Luminex® multiplexed binding assay.

Description
H3.3 Antibody, SNAP-Certified™ for CUT&RUN is an antibody to histone variant H3.3. H3.3 is enriched in promoters and enhancers of active genes as well as transcriptionally inactive heterochromatin, reflecting the diverse functions of this unique histone variant [1]. The antibody is highly specific for H3.3 without cross-reacting with canonical H3.1. Binding is not impacted by methylation or mutations at amino acids H3.3K27 or H3.3K36 (Figure 1).
H3.3 differs from canonical H3.1 at just five amino acids (31, 87, 89, 90, 96). Most of these changes are located in the inaccessible histone core, making them unfit epitopes for chromatin mapping experiments. The SNAP-Certified™ H3.3 antibody specifically interacts with amino acid 31, where a serine is substituted for alanine, allowing clear distinction between H3.3 and H3.1 in chromatin mapping experiments.
The H3.3 antibody meets EpiCypher’s SNAP-Certified™ criteria for specificity and efficiency in CUT&RUN. This requires <20% cross-reactivity to other histone variants, determined using SNAP-CUTANA™ Spike-in Controls (Figure 2). High target efficiency is confirmed by consistent genomic enrichment at 500k and 50k cells (Figure 3).
Note: This antibody is sensitive to dithiothreitol (DTT).
Validation Data - CUT&RUN
Figure 1: Luminex multiplexed specificity
profiling
Histone H3.3 antibody was assessed using a Luminex® multiplexed binding assay. The panel of targets
comprises biotinylated designer nucleosomes individually coupled to color-coded Luminex MagPlex®
beads. Antibody binding to nucleosomes was tested in multiplex at a 1:250 dilution and detected with
anti-IgG*Phycoerythrin (BioLegend 406421). Mean fluorescence intensity was quantified using Luminex
FlexMAP 3D®. H3.3 antibody does not bind H3.1 and H3.3S31phos, as expected. H3.3 antibody binding is
not affected by mutations or modifications of adjacent residues.
Figure 2: SNAP specificity analysis in
CUT&RUN
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 variant panel (x-axis). Data are expressed as a
percent relative to on-target recovery (H3.3 set to 100%).
Figure 3: H3.3 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). Two representative loci of the top called peaks
are shown. 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) and Histone
Variant Panel spiked-in prior to the addition of 0.5 µg of either IgG negative
control (EpiCypher 13-0042), H3K4me3 positive control (EpiCypher 13-0060), or H3.3 antibodies. The
experiment was performed using the CUTANA™ ChIC/CUT&RUN Kit v4 (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 5.2 million reads (IgG 500k cell
input), 2.5 million reads (H3K4me3 500k cell input), 7.0 million reads (H3.3 500k cell input), and
3.7
million reads (H3.3 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.
