| 使用方法 | Validated Applications: ChIP: 10 µl per ChIP ChIP-Seq: 5 µl each WB: 1:500 - 1:5,000 dilution Published Applications: ChIP-Seq See references for more information. Individual optimization may be required. The modENCODE and NIH Roadmap Epigenomics Mapping Consortiums have implemented rigorous standardization criteria for all assays and reagents to be used. As part of this initiative, antibody specificity testing and the ability of the antibodies to work in ChIP-Seq were assessed in a large-scale study. This Histone H3 dimethyl Lys79 antibody was validated for ChIP-Seq in the study (see reference). |

| 免疫原 | This Histone H3 dimethyl Lys79 antibody was raised against a peptide including dimethyl-lysine 79 of histone H3. | |
| 背景 | Histone H3 is one of the core components of the nucleosome. The nucleosome is the smallest subunit of chromatin and consists of 147 base pairs of DNA wrapped around an octamer of core histone proteins (two each of Histone H2A, Histone H2B, Histone H3 and Histone H4). Chromatin is subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression. Lysine 79 of histone H3 can be mono-, di-ortrimethylated by Dot1 methylase; methylation at this residue acts as a marker of inactive chromatin regions that is critical for transcriptional silencing, and it is thought that silencing proteins such as Sir3 function by blocking Dot1 methylation. | |

Histone H3K79me2 antibody (pAb) tested by ChIP-chip. ChIP was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with chromatin from 3 million HeLa cells and 5 µl of antibody. ChIP DNA was amplified by WGA, labeled and hybridized to a human tiling array. The images are characteristic of the binding patterns seen at many genes across the genome with the highest binding occurring at the promoter and a gradual decrease as signal moves into the gene body. | |
Histone H3 dimethyl Lys79 antibody (pAb) tested by ChIP analysis. Chromatin IP performed using the ChIP-IT® Express Kit (Catalog No. 53008) and HeLa chromatin (1.5 x 106 cell equivalents per ChIP) using 10 µl of Histone H3 dimethyl Lys79 antibody or the equivalent amount of rabbit IgG as a negative control. Real time, quantitative PCR (RT-qPCR) was performed on ChIP DNA using a primer pair specific for the indicated gene. Data are presented as Fold Enrichment of the ChIP antibody signal compared to the negative control IgG (which has been normalized to 1.0) using the ddCT method. | |
Histone H3 dimethyl Lys79 antibody tested by dot blot analysis. Dot blot analysis was used to confirm the specificity of Histone H3 dimethyl Lys79 antibody for dimethyl lysine 79 of histone H3. Decreasing amounts of peptides corresponding to the region around lysine 79 of histone H3 were spotted onto PVDF and probed with the antibody at a 1:10,000 dilution. Lane 1: Unmodified Lys79 peptide. Lane 2: Monomethyl Lys79 peptide. Lane 3: Dimethyl Lys79 peptide. Lane 4: Trimethyl Lys79 peptide. |
