The 147 bp 601 sequence, which contains a 5’ biotin-TEG\n group, has high affinity for histone octamers and is useful for\n nucleosome assembly [1]. Histone H2A contains a glutamate-to-lysine\n (E-to-K) substitution at position 92 (H2AE92K). H2AE92 is among key\n residues forming a negatively charged region on the nucleosome\n surface named the “acidic patch”. The acidic patch is a conserved\n interaction hub for neighboring nucleosomes and nucleosome binding\n proteins, often via salt bridges with arginine anchors, and is\n functionally critical in chromatin condensation and chromatin\n remodeling [2-4]. H2AE92 resides in the H2A C-terminal extension and\n is associated with nucleosome binding factors such as histone H4\n N-terminal tail, LANA, RCC1, IL-33, SIR3, HMGN2, and remodeling\n ATPases [2-4]. H2AE92K disrupts binding with SMARCB1 [5].\n </p>\n </div>\n </div>\n </div>\n <div id=\"prodAccordion\">\n <div id=\"ProductDescription\" class=\"Block Panel current\">\n <h3 class=\"sub-title1\">Validation Data</h3>\n <div\n class=\"ProductDescriptionContainer product-droppdown__section-description-specific\"\n >\n <section class=\"image-picker\">\n <div class=\"image-picker__left\">\n <div\n class=\"image-picker__main-content_active image-picker__main-content\"\n >\n <div class=\"image-picker__header-content\">\n <button class=\"image-picker__left-arrow\">\n <svg\n class=\"image-picker__svg-left\"\n width=\"24\"\n height=\"24\"\n viewBox=\"0 0 24 24\"\n >\n <path\n d=\"M16.67 0l2.83 2.829-9.339 9.175 9.339 9.167-2.83 2.829-12.17-11.996z\"\n />\n </svg>\n </button>\n <a\n href=\"/content/images/products/nucleosomes/16-0030-protein-gel-data-test.jpeg\"\n target=\"_blank\"\n class=\"image-picker__main-image-link\"\n ><img\n alt=\"16-0030-protein-gel-data-test\"\n src=\"/content/images/products/nucleosomes/16-0030-protein-gel-data-test.jpeg\"\n class=\"image-picker__main-image\"\n />\n <span class=\"image-picker__main-image-caption\"\n >(Click to enlarge)</span\n ></a\n >\n <button class=\"image-picker__right-arrow\">\n <svg\n class=\"image-picker__svg-right\"\n width=\"24\"\n height=\"24\"\n viewBox=\"0 0 24 24\"\n >\n <path\n d=\"M7.33 24l-2.83-2.829 9.339-9.175-9.339-9.167 2.83-2.829 12.17 11.996z\"\n />\n </svg>\n </button>\n </div>\n <p>\n <span class=\"image-picker__span-content\"\n ><strong>Figure 1: Protein gel data </strong><br />\n Coomassie stained PAGE gel of proteins in H2AE92K\n mononucleosome (1 µg) demonstrates the purity of the\n histones in the preparation.
