Opis ogólny
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 (Lys27) set includes the Dimethyl-Histone H3 (Lys27) antibody, a negative control rabbit supernatant, and qPCR primers which amplify a 110 bp region of human β-globin promoter. The Dimethyl-Histone H3 (Lys27) and negative controls are supplied in a scalable "per ChIP" reaction size and can be used to functionally validate the precipitation of Dimethyl-Histone H3 (Lys27)-associated chromatin.

Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. The four core histones, H2A, H2B, H3, and H4, assemble into an octamer (2 molecules of each). Subsequently, 146 base pairs of DNA are wrapped around the octamer, forming a nucleosome. Histones are modified post-translationally by the actions of enzymes in both the nucleus and cytoplasm. These modifications regulate DNA transcription, repair, recombination, and replication. The most commonly studied modifications are acetylation, phosphorylation, methylation, and ubiquitination. These modifications can alter local chromatin architecture, or recruit trans-acting factors that recognize specific histone modifications (the "histone code" hypothesis). The modifications occur predominantly on the N-terminal and C-terminal tails that extend beyond the nucleosome core particle. Histone H3 is methylated at Lys27 by EZH2, and and overexpression of EZH2 has been associated with both breast and prostate cancers. Methylation of H3K27 is involved in X chroosome inactivation, imprinting, circadian rhythms, and stem cell maintenance. H3K27me2 is a marker of classical heterochromatin.
Specyficzność
Broad species cross-reactivity expected, based on sequence identity in most species.
This antibody recognizes Histone H3 dimethylated on Lys27.
Immunogen
Epitope: Dimethyl Lys27
Peptide containing the sequence (ARme2KSA) in which me2 corresponds to dimethyl lysine at residue 27 of human histone H3.
Zastosowanie
Chromatin Immunoprecipitation:
Representative lot data.
Sonicated chromatin prepared from HeLa cells (1 X 10E6 cell equivalents per IP) were subjected to chromatin immunoprecipitation using either 2 µL of Negative Control Supernatant or 2 µL of Anti-dimethyl-Histone H3 (Lys27) and the Magna ChIP® A Kit (Cat. # 17-610).
Successful immunoprecipitation of dimethyl-Histone H3 (Lys27) associated DNA fragments was verified by qPCR using ChIP Primers, human β-globin as a positive locus, and GAPDH promoter primers as a negative locus (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 ChIP A (Cat. # 17-408) or EZ-ChIP (Cat. # 17-371) protocol for experimental details.
Western Blot Analysis:
Representative lot data.
A 1:1000-1:5000 dilution of a previous lot detected dimethyl-Histone H3 in acid extracted proteins from HeLa cells, but did not detect unmethylated recombinant Histone H3 (Catalog # 14-494).
Recombinant Histone H3 (lane 1) and HeLa cell acid precipitate (lane 2) were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-dimethyl-Histone H3 (Lys27) (1:1000 dilution).
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.
Arrow indicates dimethyl-histone H3 (~17 kDa) (Please see figures).
Peptide Inhibition Assay (PIA):
Representative lot data.
0.5-2 μM of histone H3 peptides containing dimethyl-Lys27 abolished detection of histone H3 by anti-dimethyl-Histone H3 (Lys27) (1:1000 dilution) in immunoblots of acid extracted proteins from HeLa cells.
Acid extracted proteins from HeLa cells were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-dimethyl-Histone H3 (Lys27) (lane 1) or anti-dimethyl-Histone H3 (Lys27) preabsorbed with 0.5 mM of histone H3 peptides containing the following modifications:
Lane 2: dimethyl-lysine 23
Lane 3: dimethyl-lysine 27
Lane 4: dimethyl-lysine 9
A 1:1000 dilution of the primary antibody was used.
Proteins were visualized using a goat anti-rabbit secondary antibody conjugated to HRP and a chemiluminescence detection system.
