Histone H3K27me3 antibody (mAb)
产品英文名称：Histone H3K27me3 antibody (mAb)
Active Motif Histone 组蛋白H3K27me3抗体（mAb）产品英文描述：
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 activationr 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.
This Histone H3 trimethyl Lys27 antibody was raised against a peptide containing trimethyl Lys27 of human Histone H3.
This Histone H3 trimethyl Lys27 antibody chromatin IP (ChIP) (2 - 10 µg per ChIP), immunofluorescence (0.5 - 1 µg/ml), immunoprecipitation (1 - 5 µg per IP) and Western blotting (0.5 - 2 µg/ml). See References for details.
PBS pH 7.5 containing 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic. For your convenience, a PBS only version of this antibody is also available.
