synthesized histone h1 h2 h3 h4 online manufacturer Manufacturer

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

H3K4me2 Catalog Number H3102 Lyophilized Store At -20C Or -80C Chemically synthesized histone H3 protein, corresponding to residues within 1-135 of human histone H3, dimethylation at K4. H3K4me2 is a modification thought to have a role in transcriptional memory. In CD4+ T lymphocytes, H3K4Me2 is present within gene bodies regulating cellular function, but not in those of housekeeping genes, which indicates that the modification has a role in refining the tissue-specificity
