Nucleosome, Recombinant Human, H4 Tetraacetyl dNuc Description: Mononucleosomes assembled from recombinant human histones expressed in E. coli (two each of histones H2A, H2B, H3 and H4; accession numbers: H2A-P04908; H2B-O60814; H3.1-P68431; H4-P62805) wrapped by 147 base pairs of 601 positioning sequence DNA. Histone H4 (created by a proprietary synthetic method) contains N-terminal alpha-acetylation and acetyl-lysine at positions 5, 8, 12 and 16. The nucleosome is the basic subunit of chromatin. The 601 sequence, identified by Lowary and Widom, is a 147-base pair sequence that has high affinity for histone octamers and is useful for nucleosome assembly.

Nucleosome, Recombinant Human, H4 Tetraacetyl dNuc Formulation: Nucleosome, Recombinant Human, H4 Tetraacetyl (50 µg total mass, DNA+protein, 27.3 µg protein weight) in 10 mM Tris HCl, pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, 20% glycerol. MW = 201,031 Da.

Nucleosome, Recombinant Human, H4 Tetraacetyl dNuc Storage and Stability: Stable for six months at -80°C from date of receipt. For best results, aliquot and avoid multiple freeze/thaws.

Nucleosome, Recombinant Human, H4 Tetraacetyl dNuc Application Notes: Nucleosome, Recombinant Human, H4 Tetraacetyl are highly purified and are suitable for use as substrates in enzyme screening assays or for effector protein (especially bromodomain) binding experiments. Nucleosome, Recombinant Human, H4 Tetraacetyl from EpiCypher does not contain free DNA which could alter assayed activities.
