Patents Assigned to Chromatin, Inc.
  • Publication number: 20090222947
    Abstract: The invention is generally related to methods of generating plants transformed with novel autonomous mini-chromosomes. Mini-chromosomes with novel compositions and structures are used to transform plants cells which are in turn used to generate the plant. Methods for generating the plant include methods for delivering the mini-chromosome into plant cell to transform the cell, methods for selecting the transformed cell, and methods for isolating plants transformed with the mini-chromosome. Plants generated in the present invention contain novel genes introduced into their genome by integration into existing chromosomes.

  • Patent number: 6649347
    Abstract: The invention provides efficient methods for the isolation of centromeres from potentially any organism. The methods may comprise the steps of: a) preparing a first sample of genomic DNA from a selected species; b) obtaining a plurality of methylated nucleic acid segments from the genomic DNA; and c) screening the methylated nucleic acid segments to identify a centromere nucleic acid sequence.
