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+ Trimethyl-Histone H3 (Lys9) set includes the Anti-trimethyl-Histone H3 (Lys9) antibody, a negative control antibody (purified rabbit IgG), and qPCR primers which amplify a 117 bp region within the 3’ end of the human ZNF554 gene. The trimethyl-histone H3 (Lys9) 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 (Lys9) associated chromatin.
The methylation of histones can occur on two different residues: arginine or lysine. Histone methylation can be associated with transcriptional activation or repression, depending on the methylated residue. Lysine 9 of histone H3 can be mono-, di- or trimethylated by different histone methyltransferases (HMTs) such as SuvH39H1 or G9a. This methylated lysine can be demethylated by histone demethylases as JMJD1A, LSD1 or JMJD2C. Methylation of this residue is mainly associated with transcriptional repression.

Specificity

Recognizes histone H3, Mr 17 kDa, trimethylated at lysine 9.
The immunogen sequence is identical in a wide range of animal and plant species, so broad cross-reactivity is expected.

Immunogen

The trimethyl-histone H3 (Lys9) purified antibody is made against BSA-conjugated, synthetic peptide containing the sequence …AR[me3K]S… in which me3K corresponds to trimethyl lysine 9 of human Histone H3.

Application

Chromatin Immunoprecipitation:
Sonicated chromatin prepared from 2x106 HeLa cells were subjected to chromatin immunoprecipitation using 4 μg purified antibody or normal rabbit IgG and the Magna ChIP A kit (Cat. # 17-610).
Successful enrichment of trimethyl-Histone H3 (Lys9) associated DNA fragments was verified by qPCR using ChIP Primers GAPDH flanking the human GAPDH promoter and primers targeting the promoter of human MyoD.
Please refer to the EZ-Magna ChIP A (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) kit protocols for experimental details.

Western Blot Analysis:
Recombinant Histone H3 (Lane 1) and HeLa acid extract (Lane 2) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-trimethyl-Histone H3 (Lys9), (1 μg/mL). Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system (Please see figures).

Beadlyte Histone Peptide Specificity Assay:
0.5 μg/ml of purified anti-dimethyl-Histone H3 (Lys9) was incubated with a cocktail of microspheres conjugated to histone H3 peptides with the following modifications:
1. trimethyl-lysine 9
2. dimethyl-lysine 9
3. monomethyl-lysine 9
4. Unmodified H3
Unbound antibody was then removed by filtration. Peptide antibody complexes were incubated with a PE-conjugated anti-rabbit secondary antibody. Fluorescence was read on a Luminex 100 instrument. Median Fluorescence intensity (MFI) is plotted.

Quality

Chromatin Immunoprecipitation:
Sonicated Chromatin prepared from 3x106 NIH3T3 L1 cells were subjected to chromatin immunoprecipitation using 4 µg of either normal rabbit IgG or Anti-trimethyl-Histone H3 (Lys9) antibody and the Magna ChIP A kit (Cat. #17-610). Successful enrichment of trimethyl-histone H3 (Lys9)-associated DNA fragments was verified by qPCR using ChIP Primers ZNF554 (Please see figures).
