Histone H3 (created by a proprietary semi-synthetic method) contains dimethyl-lysine at position 4. 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. *H3K4me2 has a Cys to Ala substitution at position 110.<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, H3K4me2 dNuc</b></span></span>Formulation:</b> Nucleosome, Recombinant Human, H3K4me2 (27.3 µg protein weight, 50 µg total weight) in 10 mM Tris HCl, pH 7.5, 25 mM NaCl, 1 mM EDTA, 2 mM DTT, 20% glycerol.
