High efficiency targeted in situ genome-wide profiling

摘要

A method for detecting the binding of a chromatin-associated factor of interest to a sequence of chromatin DNA in a cell, including: contacting a permeabilized cell or nucleus with a specific binding agent that specifically recognizes the chromatin-associated factor of interest, wherein the specific binding agent is linked to a nuclease that is inactive or an activatable transposome; activating the nuclease or transposase, thereby excising the sequence of chromatin DNA bound to the chromatin- associated factor of interest; isolating the excised DNA; and determining the sequence of the excised DNA, thereby detecting binding of a chromatin-associated factor of interest to a sequence of chromatin DNA in the cell.
