The CD226:CD155 Homogeneous Assay Kit is designed to measure the inhibition of CD226 binding to CD155 (PVR). The CD226:CD155 Homogeneous Assay Kit comes in a convenient AlphaLISA® format with purified biotinylated CD226, His-tagged CD155, and assay buffer to perform a total of 384 reactions. With this kit, only three simple steps on a microtiter plate are required. First, a sample containing CD226 and an inhibitor of choice is incubated with the CD155 for 60 minutes. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.
