Histone H3 (created by a proprietary synthetic method) contains butyryl-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\nhigh affinity for histone octamers and is useful for nucleosome assembly and contains a 5’ biotin-TEG group.<br /><br /></span></span></td></tr><tr>\n <td valign=\"top\"><span style=\"font-family: Arial; \" class=\"Apple-style-span\"><span style=\"font-size: 12pt; \" class=\"Apple-style-span\"><b><span class=\"Apple-style-span\" style=\"font-family: Arial; \"><span class=\"Apple-style-span\" style=\"font-size: 12pt; \"><b>Nucleosome, Recombinant Human, H3K27bu</b></span></span> dNuc Biotinylated Formulation:</b> Nucleosome, Recombinant Human, H3K27bu (27.3 μg protein weight, 50 μg DNA+protein) in μl 10 mM Tris HCl,\npH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, 20% glycerol.
