The TRIM24 Inhibitor Screening Assay Kit is designed to measure the inhibition of TRIM24 binding to its substrate. The key to the TRIM24 Inhibitor Screening Assay Kit is the specific binding of the TRIM24 bromodomain to an acetylated histone substrate. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing TRIM24 and an inhibitor of choice is incubated with the biotinylated substrate. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.
