| 免疫原 | This Histone H3 monomethyl Lys27 antibody was raised against a peptide including monomethyl-lysine 27 of human 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). Histone H1 is a linker histone, present at the interface between the nucleosome core and DNA entry/exit points. Histone H1 is responsible for establishing higher-order chromatin structure. 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. 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 27 of histone H3 can be mono-, di- or trimethylated (Histone H3 monomethyl Lys27, Histone H3 dimethyl Lys27 or Histone H3 trimethyl Lys27) by different histone methyltransferases such as EZH2 or NSD3. Methylation of this residue is mainly associated with transcriptional repression. | |

Histone H3 monomethyl Lys27 antibody tested by Western blot. HeLa acid extract (10 µg per lane) probed with Histone H3 monomethyl Lys27 antibody (1:2,000 dilution). | |
Histone H3 monomethyl Lys27 pAb tested by dot blot analysis. Dot blot analysis was used to confirm the specificity of Histone H3 monomethyl Lys27 pAb for monomethyl Lys27 histone H3. Methylated peptides corresponding to the immunogen and related sequences derived from histone H3 were spotted onto PVDF and probed with the antibody at 1:1,000. The amount of peptide (picomoles) spotted is indicated next to each row. Lane 1: unmodified Lys4 peptide. Lane 2: monomethyl Lys4. Lane 3: dimethyl Lys4; Lane 4: trimethyl Lys4. Lane 5: monomethyl Lys9. Lane 6: unmodified Lys9. Lane 7: dimethyl Lys9. Lane 8: trimethyl Lys9. Lane 9: unmodified Lys27. Lane 10: monomethyl Lys27. Lane 11: dimethyl Lys27. Lane 12: trimethyl Lys27. |
