  • Patent number: 11965890
    Abstract: One aspect of the present invention describes materials and methods of quantitatively measuring the density or percent occupancy of DNA binding proteins such as histones, histone variants, histone post translational modifications and transcription factors in chromatin at given DNA loci. One embodiment measures a factor's average quantity at specific gene loci, and controls for a number of pitfalls concerning antibody quality and handling issues. Other embodiments include calibrating and quantifying chromatin immunoprecipitation assays, assessing an affinity reagent specificity, as well as required reagents and their formulation in kits. Another embodiment allows for the diagnosis of a condition or disease by measuring the density of a histone modification at a genomic locus.
