Nucleosome, Recombinant Human, H3K27ac 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 H3 (created by a proprietary synthetic method) contains acetyl-lysine at position 27. 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, H3K27ac dNuc Formulation: Recombinant H3K27ac mononucleosomes (27.4 µg protein weight, 50 µg DNA+protein) in 10 mM Tris-HCl pH 7.5, 1 mM EDTA, 25 mM NaCl, 2 mM DTT, & 20% glycerol. Nucleosome molecular weight = 200,075 Da.

Nucleosome, Recombinant Human, H3K27ac 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, H3K27ac dNuc Application Notes: Nucleosome, Recombinant Human, H3K27ac are highly purified and are suitable for use as substrates in enzyme screening assays or for effector protein (bromo and YEATS domains) binding experiments.

Western Blot Data: Western Analysis of Nucleosome, Recombinant Human, H3K27ac. Top Panel: Unmodified H3 (Lane 1) and H3K27ac containing nucleosomes (Lane 2) were probed with an anti-H3K27ac antibody and analyzed via ECL readout. Only the H3K27ac sample produced a detectable signal. Bottom Panel: Detail from Coomassie stained gel showing unmodified nucleosomes (Lane 1) and H3K27ac nucleosomes (Lane 2).
