H3K36me1 Catalog Number H3110 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, monomethylation at K36. The methylation of H3K36 has particularly had effects in transcriptional repression, alternative splicing, dosage compensation, DNA replication and repair, DNA methylation, and the transmission of the memory of gene expression from parents to offspring during development. set2 mutants

H4-K20ac Catalog Number H4204 Lyophilized Store At -20C Or -80C Chemically synthesized histone H4 protein, corresponding to residues within 1-102 of human histone H4, acetylation at K20. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. H4K20ac is associated with gene repression in human cells. Unlike H3K9me3, a constitutive heterochromatin mark, H4K20ac was less associated

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

H2A-K119Ub Catalog Number H1403 Store at -20C or -80C Chemically synthesized histone H2A protein (1-129,homo sampien) with mono-ubiquitination at K119. Histone modifications are associated with distinct transcription states and serve as heritable epigenetic markers for chromatin structure and function. H2A-K119Ub is characteristic of repressed developmental genes and is also tightly linked to levels of other histone marks such as lysine methylation and acetylation. Main
