Description générale

All ChIPAb+ antibodies are individually validated for chromatin precipitation, every lot, every time. Each ChIPAb+ antibody set includes control primers (tested every lot by qPCR) to biologically validate your IP results in a locus-specific context. The qPCR protocol and primer sequences are provided, allowing researchers to validate ChIP protocols when using our antibody in their chromatin context. Each set also includes a negative control antibody to ensure specificity of the ChIP reaction.
The ChIPAb+ Dimethyl-Histone H3 (Lys4) set includes the Anti-dimethyl-Histone H3 (Lys4) antibody, a negative control antibody (purified Mouse IgG), and qPCR primers which amplify a 213 bp region within the coding region of the human GAPDH gene. The dimethyl-histone H3 (Lys4) and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of dimethyl-histone H3 (Lys4)-associated chromatin.

Spécificité

Recognizes histone H3, Mr 17 kDa, dimethylated at lysine 4.
The peptide sequence is identical in a wide range of animal and plant species, so broad cross-reactivity is expected.

Immunogène

Epitope: a.a. 1-12
The dimethyl-histone H3 (Lys4) purified antibody is made against a synthetic peptide (dimethylated at Lys4) corresponding to amino acids 1-12 of histone H3.

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from HeLa cells (2 X 106 cell equivalents per IP) was subjected to chromatin immunoprecipitation using 2 µg of either normal mouse IgG, or Anti-dimethyl-Histone H3 (Lys4) antibody and the Magna ChIP G Kit (Cat. #17-611). Successful immunoprecipitation of dimethyl-histone H3 (Lys4)-associated DNA fragments was verified by qPCR using β-globin ChIP Primers versus GAPDH Coding primers (Please see figures). Data is presented as percent input of each IP sample relative to input chromatin for each antibody with the indicated primers.
Please refer to the EZ-Magna G ChIP (Cat. #17-408) or EZ-ChIP (Cat. #17-371) protocol for experimental details.

ChIP-seq Analysis:
Chromatin immunoprecipitation was performed using the Magna ChIP HiSens kit (cat# 17-10460), 2 µg Anti-dimethyl-Histone H3 (Lys4) antibody (cat# 17-677), 20 µL Protein A/G beads, and 1e6 crosslinked HeLa cell chromatin followed by DNA purification using magnetic beads. Libraries were prepared from Input and ChIP DNA samples using standard protocols with Illumina barcoded adapters, and analyzed on Illumina HiSeq instrument. An excess of sixteen million reads from FastQ files were mapped using Bowtie (http://bowtie-bio.sourceforge.net/manual.shtml) following TagDust (http://genome.gsc.riken.jp/osc/english/dataresource/) tag removal. Peaks were identified using MACS (http://luelab.dfci.harvard.edu/MACS/), with peaks and reads visualized as a custom track in UCSC Genome Browser (http://genome.ucsc.edu) from BigWig and BED files. The highest 25% of peaks identified in the 04-790 and 17-677 datasets showed 92 and 90% overlap with peaks identified in the ENCODE H3K4me2 BROAD Histone track for HeLa S3.

Western Blot Analysis:
Recombinant Histone H3 (Lane 1) and HeLa acid extract (Lane 2) were resolved by electrophoresis, transferred to PVDF membrane and probed with Anti-dimethyl Histone H3 (Lys4) (2 μg/mL).
Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP (Cat. #AP124P) and a chemiluminescence detection system.

Dot Blot Analysis:
Absurance Histone H3 Antibody Specificity Array (Cat. No. 16-667) and Absurance Histone H2A, H2B, H4 Antibody Specificity Array (Cat. No. 16-665), which contain histone peptides with various modifications were probed with Anti-dimethyl H3 (Lys4) at 2.0ug/mL (1:500) dilution. Proteins were visualized using a Donkey anti-mouse IgG conjugated to HRP and a chemiluminescence detection system.

Beadlyte Histone Peptide Specificity Assay:
0.15 μg/ml of purified anti-dimethyl-Histone H3 (Lys4),
clone CMA303 was incubated with a cocktail of microspheres
conjugated to histone H3 peptides with the following modifications:
1. unmodified H3 (K4)
2. monomethyl H3 (K4)
3. dimethyl H3 (K4)
4. trimethyl H3 (K4)
5. trimethy H3 (K27)
Unbound antibody was then removed by filtration.
Peptide antibody complexes were incubated with a
PE-conjugated anti-mouse secondary antibody.
Fluorescence was read on a Luminex 100
instrument. Median Fluorescence intensity (MFI) is plotted.
