背景介绍 Human T-cell immunoreceptor with Ig and ITIM domains (TIGIT) is a receptor that is expressed on the surface of human T cells and NK cells that binds to CD155 and CD112 on the surface of dendritic cells. Binding of TIGIT with CD155 or CD112 results in inhibition of T cell and NK cell activation. Antibodies and other agents that inhibit this signaling pathway have been shown to increase the immune response, especially in the case of certain cancers. 产品介绍 The TIGIT:CD112 Homogeneous Assay Kit is designed to measure the inhibition of human T-cell immunoreceptor with Ig and ITIM domains (TIGIT) binding to CD112 (PVRL2/Nectin-2). The TIGIT:CD112 Homogeneous Assay Kit comes in a convenient AlphaLISA® format with purified biotinylated TIGIT, His-tagged CD112, 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 TIGIT and an inhibitor of choice is incubated with the CD112 for 60 minutes. Next, acceptor beads are added, then donor beads, followed by reading the Alpha-counts.
