The ATAD2A Inhibitor Screening Assay Kit is designed to measure the inhibition of ATAD2A binding to its substrate. The key to the ATAD2A Inhibitor Screening Assay Kit is a specific binding of the ATAD2A bromodomain to the acetylated histone substrate. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing ATAD2A and an inhibitor of choice is incubated with the biotinylated substrate for thirty minutes. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.
