An Assay for Measuring Histone Variant Exchange within Nucleosomes In Vitro,One such example is H2A.Z, a highly conserved variant of H2A that is incorporated in genomic regulatory regions and contributes to control gene expression. H2A.Z variant exchange involves the removal of H2A-H2B dimers from a preassembled nucleosome and their replacement with H2A.Z-H2B dimers. A spec

Purification of Yeast Native Reagents for the Analysis of Chromatin Function-I: Nucleosomes for Recstone proteins harbor numerous post-translational modifications, which may differ between species, tissues, and growth conditions and are lacking on recombinant histones. Moreover, the physiological substrate of most enzymes that modify histones is chromatin and the majority of these enzymes need to

Purification of Yeast Native Reagents for the Analysis of Chromatin Function-II: Multiprotein Compland there is an intricate cross-talk between different marks as they are recognized by specific reader modules present in a large number of nuclear factors. In order to precisely dissect these processes in vitro native reagents like purified chromatin and histone modifying/remodeling enzymes are req

Analytical Ultracentrifuge Analysis of Nucleosomes Assembled from Recombinant, Acid-Extracted, HPLCetics demand the availability of methods for a rapid and efficient nucleosome reconstitution to analyze their structural and functional implications. Here we describe a method suitable for this purpose, starting from bacterially expressed histones, solubilized by acid and purified by reversed-phase

Glycogen

SILAC-Based Quantitative Strategies for Accurate Histone Posttranslational Modification Profiling Ay (MS) has emerged as a versatile technology for the analysis of histones, contributing to the dissection of hPTMs, with special strength in the identification of novel marks and in the assessment of modification cross talks. Stable isotope labeling by amino acid in cell culture (SILAC), when adapte

Production and Purification of Antibodies Against Histone Modifications,ly available antibodies that recognize a remarkable diversity of histone modifications. Unfortunately, many of them fail to work in certain applications or lack the high degree of specificity required of these reagents. The production of affinity-purified polyclonal antibodies against histone modifi
