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

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

H4-K20me2 Catalog Number H4101 Lyophilized Store At -20C Or -80C Chemically synthesized histone H4 protein, corresponding to residues within 1-102 of human histone H4, dimethylation at K20. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. H4K20me2 is the most common methylation state on histone H4 and was one of the earliest modified histone residues to be identified back

Types of histone modification Chromatin architecture, nucleosomal positioning, and ultimately access to DNA for gene transcription, is largely controlled by histone proteins. Each nucleosome is made of two identical subunits, each of which contains four histones: H2A, H2B, H3, and H4. Meanwhile, the H1 protein acts as the linker histone to stabilize internucleosomal DNA and does not form part of the nucleosome itself. Histone proteins undergo post-translational modification

H2B-K34Ub Catalog Number H2401 Store at -20C or -80C Chemically synthesized histone H2B protein corresponding to residues within 1-125 of human histone H2B with K34 monoubiquitination. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. H2B-K34ub modification is sufficient to promote selective eviction of only one H2A/H2B dimer independently of histone-binding agents. H2B K34
