This present invention relates to methods for carrying out chromatin mapping assays that use enzymes to incorporate barcoded DNA at targeted genomic regions followed by long-read sequencing (e.g., Third Generation Sequencing (TGS)). This approach enables the mapping of chromatin targets using TGS and can be used for a wide range of elements or features, including histone post-translational modifications, chromatin associated proteins, nucleosome positioning, and chromatin accessibility. The invention further relates to kits and reagents for carrying out the methods on chromatin samples that include one or more cells.

Methods, compositions and kits are provided to amplify the amount of genomic methylated DNA can by subsequently analyzed and/or sequenced. It has particular use with small amounts of DNA, including, but not limited to cell free DNA samples. In some embodiments, the ratio of polymerase and methyltransferase is controlled in order to provide maximum yields. In some embodiments, a dual primase/polymerase is used.
