Description
General description
17 kDa
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+ Monomethyl-Histone H3 (Lys27) set includes the anti-monomethyl-histone H3 (Lys27) antibody, a negative control antibody (normal rabbit serum), and qPCR primers which amplify a 110 base pair region within the promoter of the human β-globin gene. The monomethyl-histone H3 (Lys27) and negative control antibodies are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of monomethyl-histone H3 (Lys27)-associated chromatin.
Immunogen
The monomethyl-histone H3 (Lys27) antiserum is made against a synthetic 2X-branched peptide containing the sequence…ARmeKSA…in which meK corresponds to monomethyl-lysine 27 of human histone H3.
Application
Chromatin Immunoprecipitation:
Successful immunoprecipitation of monomethyl-histone H3 (Lys27) associated DNA fragments was verified by qPCR using control ChIP Primers flanking the human GAPDH promoter or primers amplifying the promoter of human β-globin, which is transcriptionally inactive in HeLa cells (Please see figures). Percent Input relative to standard curves for each qPCR primer set are shown, with immunoprecipitated DNA from control serum shown as (-) and monomethyl- histone H3 (Lys27) as (+).
Please refer to the EZ-Magna A ChIP (Cat. #17-408) or EZ-ChIP (Cat. #17-371) protocol for experimental details.
Western blot analysis and peptide inhibition:
HeLa Acid extract was resolved by electrophoresis, transferred to nitrocellulose and probed with Anti-Monomethyl-Histone H3 (Lys27) (1:5000, Lane 1) or preincubated with 0.4 μM Histone H3 peptide with following modifications:
Lane 2: Linear non-modified
Lane 3: Branched monomethyl
Lane 4: Linear monomethyl
Lane 5: Branched dimethyl
Lane 6: Linear dimethyl
Lane 7: Branched trimethyl
Lane 8: Linear trimethyl
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system (Please see figures).
