H3-S10ph Catalog Number H3301 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, acetylation at K122. H3K122ac can be sufficient to stimulate transcription and that mutation of H3K122 impairs transcriptional activation. H3K122ac defines genome-wide genetic elements and chromatin features associated with active transcription. H3K122ac is catalyzed by the coactivators p300/CBP and can be

H2B-K120Ub,Lyophilized,Catalog Number: H3100,Store at -20C or -80C This product is an expressed human H3 protein composed of 135 amino acids. Histone H3 is one of the five main histones involved in the structure of chromatin in eukaryotic cells. Featuring a main globular domain and a long N-terminal tail, H3 is involved with the structure of the nucleosomes of the 'beads on a string' structure. Histone proteins are highly post-translationally modified, however Histone H3 is

H3-K4me1,Lyophilized,Catalog Number: H3101,Store at -20C or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, monomethylation at K4. H3K4me1 is an epigenetic modification to the DNA packaging protein Histone H3. It is a mark that indicates the mono-methylation at the 4th lysine residue of the histone H3 protein and often associated with gene enhancers. H3K4me1 is enriched at active and primed enhancers. Transcription

H3K9me3 Catalog Number H3106 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, trimethylation at K9. H3K9me3 is an epigenetic modification to the DNA packaging protein Histone H3. It is a mark that indicates the tri-methylation at the 9th lysine residue of the histone H3 protein and is often associated with heterochromatin. Nomenclature Abbr. Meaning H3 H3 family of histones K standard

H3K27me2 Catalog Number H3108 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, dimethylationat K27. H3K27me2 is broadly distributed within the core histone H3 and is believed to play a protective role by inhibiting non-cell-type specific enhancers. Ultimately, this leads to the inactivation of transcription. In mouse embryonic stem cells, H3K27me2 is the dominant modification form,

H3-K64ac Catalog Number H3203 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, acetylation at K64. Histone H3 is reported to be acetylated at Lys64 (H3K64ac) by p300 co-activator. In addition, H3K64ac is found enriched at the transcriptional start sites of active genes, consistent with a transcriptional activation modification opposite of its repressive counterpart H3K64me3.

H3-K36me3 Catalog Number H3113 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, Asymmetric dimethylation at R42. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. H3R42me2a is a histone modification with positive transcriptional effects. Nucleosomes containing H3R42me2a can stimulate

H3-K56ac Catalog Number H3201 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, acetylation at K56. H3K56ac is a covalent modification known as a mark of newly replicated chromatin as well as replication-independent histone replacement. H3K56ac is important for chromatin remodeling and serves as a marker of new nucleosomes during DNA replication but its role in the cell cycle is debated.

H3-K27me1 Catalog Number H3107 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, monomethylation at K27. H3K27me1 is linked to promotion of transcription and is seen to accumulate in transcribed genes. Histone-histone interactions play a role in this process. Regulation occurs via Setd2-dependent H3K36me3 deposition. H3K27me1 shows an inverse distribution to H3K27me3 that defines the

H3K4me3 Catalog Number H3103 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, trimethylation at K4. H3K4me3 is commonly associated with the activation of transcription of nearby genes. H3K4 trimethylation regulates gene expression through chromatin remodeling by the NURF complex. This makes the DNA in the chromatin more accessible for transcription factors, allowing the genes to be
