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.
Cluster of Differentiation 86 (also known as CD86 and B7-2) is a protein expressed on antigen-presenting cells (APC) that provides costimulatory signals necessary for T cell activation and survival. It is the ligand for two proteins at the cell surface of T cells, CD28 and CTLA4 (cytotoxic T-lymphocyte-associated protein 4). Binding of this protein with CD28 is a costimulatory signal for activation of the T-cell. CD86 works in tandem with CD80 to prime T cells. Recent studies have revealed that CD86 promotes the generation of a mature APC repertoire and promotes APC function and survival. Furthermore, the CD86 proteins are also involved in innate immune responses by activating NF-κB-signaling pathway in macrophages. CD86 thus is regarded as a promising candidate for immune therapy.

One approach to immunotherapy is the modulation of immune checkpoints that are critical in regulating the degree and duration of immune system responses and preventing autoimmunity.
In this application note, you will learn:
Immune checkpoints serve a critical role in the immune system to prevent autoimmunity and manage the degree and duration of an immune response. Cytotoxic T-Lymphocyte-associated protein 4 (CTLA-4 or CD152) is an inhibitory transmembrane protein involved in an immune checkpoint of significant inte ...
