Nucleosome, Recombinant Human, H2AR3me2s 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; H3.1-P68431; H4-P62805) wrapped by 147 base pairs of 601 positioning sequence DNA. Histone H2A (created by a proprietary synthetic method) contains symmetric dimethyl-arginine at position 3. 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.

Nucleosome, Recombinant Human, H2AR3me2s dNuc Biotinylated Formulation: Nucleosome, Recombinant Human, H2AR3me2s (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 = 199,859.26 Da.

Nucleosome, Recombinant Human, H2AR3me2s 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, H2AR3me2s dNuc, Biotinylated Application Notes: Nucleosome, Recombinant Human, H2AR3me2s dNucs are highly purified and are suitable for use as substrates in enzyme screening assays or for effector protein binding experiments. Nucleosome, Recombinant Human, H2AR3me2s dNucs from EpiCypher does not contain free DNA which could alter assayed activities.
