This antibody meets EpiCypher’s "CUTANA Compatible" criteria for performance in Cleavage Under Targets and Release Using Nuclease (CUT&RUN) and/or Cleavage Under Targets and Tagmentation (CUT&Tag) approaches to genomic mapping. Every lot of a CUTANA Compatible antibody is tested in the indicated approach using EpiCypher optimized protocols and determined to yield peaks that show a genomic distribution pattern consistent with reported function(s) of the target protein. JUN/c-Jun heterodimerizes with proteins of the FOS family to form an AP-1 transcription complex and binds to the AP-1 consensus motif [1]. JUN/c-Jun antibody produces CUT&RUN peaks above background primarily in intronic, intergenic, and promoter regions (Figure 1) that overlap with known JUN/c-Jun DNA-binding motifs (Figure 2).

Validation Data

CUT&RUN was performed on 500k HeLa cells with 0.5 µg of either JUN/c-Jun or IgG negative control (EpiCypher 13-0042) antibodies using the CUTANA™ ChIC/CUT&RUN Kit v2.0 (EpiCypher 14-1048). 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). 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 5.1 million reads (IgG), 12.1 million reads (JUN/c-Jun), and 6.2 million reads (H3K4me3). Data were aligned to the hg19 genome using Bowtie2. Data were filtered to remove duplicates, multi-aligned reads, and ENCODE DAC Exclusion List regions.

Figure 1: JUN/c-Jun peaks in CUT&RUN
CUT&RUN was performed as described above. Peaks were called with MACS2. Heatmaps show JUN/c-Jun peaks relative to IgG negative control antibody in aligned rows ranked by intensity (top to bottom) and colored such that red indicates high localized enrichment and blue denotes background signal (left). The number of peaks that fall into distinct classes of functionally annotated genomic regions are shown (right).

Figure 2: JUN/c-Jun transcription factor binding motif analysis in CUT&RUN
Fra1(bZIP) /BT549-Fra1-ChIP-Seq(GSE46166)/Homer consensus motif, represented as a sequence logo position weight matrix, was the top called motif significantly enriched under JUN/c-Jun CUT&RUN peaks (left). The number of JUN/c-Jun peaks containing the consensus motif from the left panel is represented by a Venn Diagram (right).

Figure 3: JUN/c-Jun 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). Three representative loci of the top called peaks are shown.

Figure 5: Immunoprecipitation data
EpiCypher JUN/c-Jun antibody (3 µg/mg lysate) was used to immunoprecipitate whole cell lysates (1 mg, 20% of IP loaded) isolated from HEK293T cells. A negative control IgG antibody and positive control antibody targeting a different JUN/c-Jun epitope (Bethyl Laboratories) were also used to demonstrate the specificity of the IP. For blotting immunoprecipitates, EpiCypher JUN/c-Jun antibody was used at a dilution of 1:200.
