The SMARCA2 Inhibitor Screening Assay Kit is designed to measure the inhibition of SMARCA2 binding to its substrate. The key to the SMARCA2 Inhibitor Screening Assay Kit is the specific binding of the SMARCA2 bromodomain to the acetylated histone substrate. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing SMARCA2 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.
