Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac dNuc, Biotinylated Description: Mononucleosomes assembled from recombinant human histones expressed in E. coli (two each of histones H2A, H2B, H3 and H4; accession numbers: H2A-P04908; H2BO60814; H3.2-Q71DI3*; H4-P62805) wrapped by 147 base pairs of 601 positioning sequence DNA. Histone H3 (created by a proprietary semi-synthetic method) contains acetylated lysine at positions 4, 9, 14, and 18 and H4 (created by a proprietary synthetic method) contains acetylated 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 and contains a 5’ biotin-TEG group. *H3K4,9,14,18ac has a Cys to Ala substitution at position 110.

Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac dNuc Biotinylated Formulation: Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac (27.3 μg protein weight, 50 μg DNA+protein) in μl 10 mM Tris HCl, pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, 20% glycerol. MW = 200,543 Da.

Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac dNuc, Biotinylated 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, H3K4,9,14,18ac/H4K5,8,12,16ac dNuc, Biotinylated Application Notes: Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac dNucs are highly purified and are suitable for use as substrates in enzyme screening assays or for effector protein binding experiments. Nucleosome, Recombinant Human, H3K4,9,14,18ac/H4K5,8,12,16ac dNucs from EpiCypher does not contain free DNA which could alter assayed activities.
