The CECR2 Inhibitor Screening Assay Kit is designed to measure the inhibition of CECR2 binding to its substrate. The key to the CECR2 Inhibitor Screening Assay Kit is the highly specific binding of the CECR2 bromodomain to the acetylated histone substrate. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing CECR2 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.
