ChIPAb+ Trimethyl-Histone H3 (Lys4) - ChIP Validated Antibody and Primer Set

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+ Trimethyl-Histone H3 (Lys4) set includes the Anti-trimethyl-Histone H3 (Lys4) antibody, a negative control antibody (purified Mouse IgG), and qPCR primers which amplify a 166 bp region within the promoter of the human GAPDH gene. The trimethyl-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 trimethyl-histone H3 (Lys4)-associated chromatin.

The previously assigned protein identifier Q66I33 has been merged into P84243. Full details can be found on the UniProt database.

Trimethyl histone H3 at ~17 kDa

Epitope: a.a. 1-12

The trimethyl-histone H3 (Lys4) purified antibody is made against a synthetic peptide (trimethylated at Lys4) corresponding to amino acids 1-12 of human histone H3.

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from untreated or colcemid treated HeLa cells (1 X 10⁶ cell equivalents per IP) was subjected to chromatin immunoprecipitation using 2 µg of either a normal mouse IgG or Anti-trimethyl-Histone H3 (Lys4) antibody and the Magna ChIP G Kit (Cat. #17-611). Successful immunoprecipitation of trimethyl-Histone H3 (Lys4) associated DNA fragments was verified by qPCR using primers ampliflying a region of the human B-Globin promoter or using GAPDH promoter Control Primers (Please see figures). Data is presented as percent input of each IP sample relative to input chromatin for each amplicon and ChIP sample as indicated.
Please refer to the EZ-Magna G ChIP (Cat. #17-408) or EZ-ChIP (Cat. #17-371) protocol for experimental details.

Western Blot Analysis:
Representative lot data.
HeLa acid extract were resolved by electrophoresis, transferred to PVDF membrane and probed with Anti-trimethyl Histone H3 (Lys4), clone CMA304 at 1 μg/ml (lane 1) or 0.5 μg/ml (lane 2). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP (Cat. #AP124P) and a chemiluminescence detection system (Please see figures).
