AlphaLISA technology allows the detection of molecules of interest in buffer, cell culture media, serum and plasma in a highly sensitive, quantitative, reproducible and user-friendly mode. In an AlphaLISA assay, a Biotinylated Anti-Analyte Antibody binds to the Streptavidin-coated Alpha Donor beads, while another Anti-Analyte Antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

V-domain Ig suppressor of T cell activation (VISTA), also known as B7-H5 and PD-1H, is a transmembrane protein that functions as an immune checkpoint. VISTA is primarily express in white blood cells and can act either as a ligand or receptor on T-cells. Its main function is to inhibit T cell effector function and maintain peripheral tolerance. VISTA is upregulated in tumor-infiltrating lymphocytes and blocking it with an antibody has proven to stunt tumor growth in mouse melanoma models. HIV-infected individuals also display increased VISTA levels in monocytes.
