General description

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+ Histone H3 (Unmodified Lys4) set includes the Anti-Histone H3 (unmodified Lys4) antibody, a negative control antibody (purified Mouse IgG), and qPCR primers which amplify a 110 bp region within the promoter of the human β-globin gene. The histone H3 (Unmodified Lys4) and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of histone H3 (Unmodified Lys4)-associated chromatin.
Histone H3 at ~17 kDa

Immunogen

Epitope: a.a. 1-12
The histone H3 (Unmodified Lys4) purified antibody is made against a synthetic peptide 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- Histone H3 (Unmodified Lys4) antibody and the Magna ChIP G Kit (Cat. #17-611). Successful immunoprecipitation of histone H3 associated DNA fragments was verified by qPCR using β-globin ChIP Primers versus GAPDH Promoter Control Primers. Data is presented as percent input of each IP sample relative to input chromatin, with the indicated primer sets (Please see figures).

Western Blot Analysis:
Acid extracted proteins from HeLa cells (Lane 1) and Recombinant Histones (Lane 2-6) were resolved by electrophoresis, transferred to PVDF membrane and probed with anti-Histone H3 (Unmodified Lys4) (0.1 μg/ml). Proteins were visualized using a goat-anti mouse secondary antibody conjugated to HRP (Cat. #AP124P) and a chemiluminescence detection system (Please see figures).

This ChIPAb+ Histone H3 (Unmodified Lys4) -ChIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.

Biochem/physiol Actions

Recognizes unmodified histone H3 (Lys4), Mr 17 kDa. Epitope specificity of antibody as determined by ELISA maps near Lys4. Antibody tolerates modifications on Lys9 and Ser10 but not Lys4 or Thr31.
The peptide sequence is identical in a wide range of animal and plant species, so broad cross-reactivity is expected.

Packaging

25 assays per kit, ~2μg per chromatin immunoprecipitation

Technical Guide to Chromatin Immunoprecipitation: Critical Factors for Success

Advance your Epigenetics Research

Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms. Epigenetic regulation allows a cell to vary its response based on its biological and environmental contexts. Epigenetic changes can effect transcriptional and post-transcriptional regulation via mechanisms such as histone modification, chromatin and nucleosome remodeling, DNA methylation, and small and non-coding RNA-mediated regulation. These mechanisms, in cooperation with transcription factors and other nucleic acid-binding proteins, regulate gene expression. Epigenetic mechanisms of gene regulation impacts diverse areas of research—from agriculture to human health. Common epigenetic assays such as chromatin immunoprecipitation (ChIP) and RNA immunoprecipitation (RIP) rely on high quality antibodies that recognize specific epigenetic modifications for accurate results. EMD Millipore offers over 100 ChIPAb+™ and RIPAb+™ validated antibody kits that are quality tested on ChIP/RIP assays and are conveniently provided with control qPCR primers and negative control antibodies to ensure first time ChIP/RIP success.

Shaping Epigenetics Discovery - Epigenetics Product Selection Brochure

"Epigenetics describes heritable changes in gene expression caused by non-genetic mechanisms instead of by alterations in DNA sequence. These changes can be cell- or tissue-specific, and can be passed on to multiple generations. Epigenetic regulation enriches DNAbased information, allowing a cell to vary its response across diverse biological and environmental contexts. Although epigenetic mechanisms are primarily centered in the nucleus, these mechanisms can be induced by environmental signals such as hormones, nutrients, stress, and cellular damage, pointing to the involvement of cytoplasmic and extracellular factors in epigenetic regulation."
