  • Patent number: 11840741
    Abstract: Provided herein, among other things, are various compositions and methods for analyzing chromatin. In some embodiments, the composition may comprise a mixture of a nicking enzyme, four dNTPs, at least one labeled dNTP and, optionally, a polymerase. In some embodiments, this method may comprise: obtaining a sample comprising chromatin, reacting the sample with the composition to selectively label the open chromatin in the sample, and analyzing the labeled sample.
    Type: Grant
    Filed: November 9, 2021
    Date of Patent: December 12, 2023
    Assignee: New England Biolabs, Inc.
    Inventors: Chaithanya Ponnaluri, Hang-Gyeong Chin, Pierre O. Esteve, Sriharsa Pradhan
  • Publication number: 20230089237
    Abstract: Compositions, methods and kits are provided for identifying the presence and location of a target in chromosomal DNA. A nicking endonuclease fused to a binding domain that binds to a constant region of an antibody (NEFP) is provided that may be used for binding to a target directly or via an antibody that binds to the target. The target may be a protein or structural feature of the DNA and its presence and location may correspond to a phenotype and/or pathology in a biopsy or other cell sample for diagnostic purposes. The background is reduced by the addition of a glycoaminoglycan (GAG) that reversibly inhibits binding of the NEFP to DNA. Nick translation in the presence of a strand displacing polymerase enables the incorporation of tagged nucleotides that (i) blocks re-nicking; (ii) facilitates immobilization of DNA fragments around the target for sequencing; and/or (iii) enables dye labelling of the chromosomal DNA within the cell nuclei for analysis by microscopy.
