The panel consists of two nucleosomes containing\n unmodified histone H3 or 3xHA-H3 fusion, each wrapped with two uniquely barcoded DNA templates (A and B, for\n an internal technical replicate). The nucleosomes are individually conjugated to paramagnetic beads and\n pooled into a single panel for convenient one-step spike-in to CUT&RUN reactions. The panel is added\n alongside ConA-immobilized cells just prior to the addition of anti-HA or IgG negative control antibodies\n (see <strong>Application Notes</strong> and <strong>Table 1</strong>). The release of genomic chromatin and\n the barcoded nucleosomes by\n pAG-MNase is dependent on the specificity of the antibody used. After sequencing, the relative read count of\n recovered HA vs. unmodified nucleosomes provides a quantitative metric of on- vs. off-target recovery\n (<strong>Figure 2</strong>), thereby gauging experimental success and guiding troubleshooting efforts.

In\n Brief:</em>\n </p>\n <p>\n <u><strong>Product Use:</strong></u> Use the SNAP-CUTANA™ HA Tag Panel for reactions containing <a href=\"/products/antibodies/cutana-cut-run-compatible-antibodies/ha-tag-cutana-cut-and-run-antibody\" target=\"_blank\">HA</a> and <a\n href=\"/products/nucleosomes/snap-cutana-spike-in-controls/cutana-igg-negative-control-antibody-for-cut-run-and-cut-tag\">IgG</a>\n antibodies. Just before antibody addition in CUT&RUN, gently pipette to resuspend beads (do\n not vortex), then spike in 2 μL per 500k cells. If using less than the standard number of cells, decrease\n the amount of SNAP-CUTANA spike-in linearly by preparing a “working stock” dilution of the panel in Antibody\n Buffer, made fresh the day of use (<strong>Table 1</strong>). Adjust spike-in volume as needed aiming for\n the spike-in\n barcodes to comprise ~1% of the total unique sequencing reads. Table 1 gives recommended dilution amounts\n for varying numbers of starting cells, but optimization may be required for user-specific conditions.\n </p>\n\n <p>\n <u><strong>Data Analysis:</strong></u> Detailed instructions are in the SNAP-CUTANA™ Spike-in User Guide (see <strong>Documents & Resources</strong> section below). Perform paired-end sequencing for a minimum of 50 bases. The Widom\n 601 DNA and DNA barcodes are distinct from human, mouse, fly, and yeast genomes such that they can be\n readily distinguished from sample chromatin. A shell script (.sh file extension) for spike-in alignment and\n an excel template for heatmap generation are available in the <strong>Documents & Resources</strong> section\n below. The shell\n script can be opened with any basic text editor program and contains detailed instructions hashed (#) at the\n beginning of the document. Make sure to copy and paste the R1 & R2 echo loop so there is a set for each\n reaction being analyzed.\n </p>\n </div>\n </div>\n </div>\n <div id=\"prodAccordion\">\n <div id=\"ProductDescription\" class=\"Block Panel\">\n <h3 class=\"sub-title1\">References</h3>\n <div class=\"ProductDescriptionContainer product-droppdown__section-description\">\n <strong>Background References:</strong>\n <br />\n [1] Lowary & Widom <em>J.

Description
The SNAP-CUTANA™ HA Tag Panel of spike-in controls for CUT&RUN offers an in-assay control to validate anti-HA antibodies and confirm the success of CUT&RUN reactions involving HA epitope-tagged chromatin proteins. This essential positive control guides troubleshooting to differentiate problems with HA epitope-tagging (including transgene expression, chromatin binding of the tagged protein, solvent accessibility of the tag, etc.) from technical failures in the CUT&RUN workflow. The panel consists of two nucleosomes containing unmodified histone H3 or 3xHA-H3 fusion, each wrapped with two uniquely barcoded DNA templates (A and B, for an internal technical replicate). The nucleosomes are individually conjugated to paramagnetic beads and pooled into a single panel for convenient one-step spike-in to CUT&RUN reactions. The panel is added alongside ConA-immobilized cells just prior to the addition of anti-HA or IgG negative control antibodies (see Application Notes and Table 1). The release of genomic chromatin and the barcoded nucleosomes by pAG-MNase is dependent on the specificity of the antibody used. After sequencing, the relative read count of recovered HA vs. unmodified nucleosomes provides a quantitative metric of on- vs. off-target recovery (Figure 2), thereby gauging experimental success and guiding troubleshooting efforts. See the most recent CUTANA™ CUT&RUN protocol and SNAP-CUTANA™ Spike-in User Guide for detailed information on workflow integration, expected results, data analysis, and troubleshooting.
Pair with our HA Tag CUTANA™ CUT&RUN Antibody for CUT&RUN success. Check it out here.
Validation Data
Figure 1: Schematic of SNAP-CUTANA™ HA Tag
Panel
The HA Tag Panel contains two nucleosomes - one has an H3 tail fusion to a 3xHA Tag epitope and one
is an unmodified control. Both octamers are wrapped with two uniquely barcoded DNA templates (A and
B). Each 250 bp DNA template contains a 123 bp 601 nucleosome positioning sequence (gray) [1], a
unique 22 bp DNA-barcode (white; 4 barcodes total), and a 5’ biotin-TEG. The 5’ and 3’ linkers
(blue) are compatible with cleavage by pAG-MNase (EpiCypher 14-1048, 15-1016) during CUT&RUN. The
nucleosomes are individually pre-conjugated to paramagnetic beads and pooled for convenient use.
Figure 2: SNAP-CUTANA™ HA Tag Panel provides an
in-assay control for CUT&RUN reactions targeting HA-tagged proteins
CUT&RUN was performed as described in Figure 5. CUT&RUN sequencing reads were
aligned to the
unique DNA
barcodes corresponding to each nucleosome in the SNAP-CUTANA™ HA Tag Panel. Data are expressed as a
percent relative to on-target recovery (HA Tag set to 100%) or total counts (IgG). IgG antibody
results demonstrate equal loading of unmodified and epitope nucleosomes in the panel. HA Tag
antibody results show selective enrichment of the HA Tag spike-in nucleosomes, validating all
CUT&RUN steps, including HA antibody binding, pAG-MNase cleavage, and wash conditions

HA Tag Panel demonstrates the purity of histones in the preparation. Sizes of molecular weight
markers and positions of the core histones (H2A, H2B, 3xHA-H3, and H4) are indicated.
Figure 5: CUT&RUN methods
CUT&RUN was performed on 500k MDA-MB-231 native cells stably expressing 3xHA-tagged GATA3 [1]*
using the CUTANA™ ChIC/CUT&RUN Kit v3 (EpiCypher 14-1048). SNAP-CUTANA™ HA Tag Panel was added just
prior to the addition of either HA Tag (0.5 µg; EpiCypher 13-2010) or IgG negative control (0.5 µg;
EpiCypher 13-0042) antibodies. Library preparation was performed with 5 ng of DNA (or
the total
amount recovered if less than 5 ng) using the CUTANA™ CUT&RUN Library Prep Kit (EpiCypher
14-1001/14-1002). Libraries were run on an Illumina NextSeq2000 with
paired-end sequencing (2x50
bp). Data were aligned to the hg19 genome using Bowtie2. Data were filtered to remove duplicates,
multi-aligned reads, and ENCODE DAC Exclusion List regions.

Technical Information
To resuspend beads, gently mix into an even suspension by pipetting; DO NOT VORTEX
Application Notes
See the most recent CUTANA™ CUT&RUN protocol and SNAP-CUTANA™ Spike-in User Guide for detailed information on workflow integration, expected results, data analysis, and troubleshooting. In Brief:
Product Use: Use the SNAP-CUTANA™ HA Tag Panel for reactions containing HA and IgG antibodies. Just before antibody addition in CUT&RUN, gently pipette to resuspend beads (do not vortex), then spike in 2 μL per 500k cells. If using less than the standard number of cells, decrease the amount of SNAP-CUTANA spike-in linearly by preparing a “working stock” dilution of the panel in Antibody Buffer, made fresh the day of use (Table 1). Adjust spike-in volume as needed aiming for the spike-in barcodes to comprise ~1% of the total unique sequencing reads. Table 1 gives recommended dilution amounts for varying numbers of starting cells, but optimization may be required for user-specific conditions.
Data Analysis: Detailed instructions are in the SNAP-CUTANA™ Spike-in User Guide (see Documents & Resources section below). Perform paired-end sequencing for a minimum of 50 bases. The Widom 601 DNA and DNA barcodes are distinct from human, mouse, fly, and yeast genomes such that they can be readily distinguished from sample chromatin. A shell script (.sh file extension) for spike-in alignment and an excel template for heatmap generation are available in the Documents & Resources section below. The shell script can be opened with any basic text editor program and contains detailed instructions hashed (#) at the beginning of the document. Make sure to copy and paste the R1 & R2 echo loop so there is a set for each reaction being analyzed.
