Accession numbers: H2AX-P16104; H2B-O60814; H3.1-P68431; H4-P62805) wrapped by 147 base pairs of 601 positioning sequence DNA. The nucleosome is the basic subunit of chromatin. H2AX is a variant of histone H2A that is phosphorylated on serine 139 by the ATM and ATR kinases in response to DNA double strand breakage. Phosphorylation of H2AX serves to recruit a number of DNA damage repair proteins, such as BRCA1 and NBS1.</span><br /> <br /> </p></td> </tr> <tr> <td valign=\"top\"><strong style=\"font-family: Arial; font-size: 16px;\">Mononucleosomes (H2AX), Human Recombinant Formulation: </strong><span class=\"Apple-style-span\" style=\"font-family: Arial;\"><span class=\"Apple-style-span\" style=\"font-size: 12pt;\">Purified recombinant mononucleosomes (50 µg total mass, 27.4 µg in 50.0 µl) in 10 mM Tris-HCl pH 7.5, 1 mM EDTA, 25 mM NaCl, 2 mM DTT and 20% glycerol.
