In an AlphaLISA assay, a biotinylated CD86 binds to the Streptavidin-coated Alpha Donor beads, while His tagged CTLA-4 is captured by Anti-His AlphaLISA Acceptor beads. When CD86 binding to CTLA-4 happens, Donor beads and Acceptor 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.\u003cbr\u003e\nHuman Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), also known as CD152 (cluster of differentiation 152), is a cell membrane receptor and a member of immunoglobulin superfamily. CTLA-4 is expressed once a T cell becomes active and modulates T cell signals by blocking the CD80 (B7.1) and CD86 (B7.2) ligands from binding to CD28. CTLA-4, functioning as an immune checkpoint, downregulates T cell immune responses. Because of its profound inhibitory role blocking CTLA-4 and CD80 or CD86 binding has been considered as promising therapeutic target for human autoimmune disease and cancers. \u003cbr\u003e\nApplication-Protein-Protein Interaction\u003cbr\u003e\nAutomation Compatible-Yes\u003cbr\u003e\nBrand-AlphaLISA\u003cbr\u003e\nDetection Modality-Alpha\u003cbr\u003e\nProduct Group-Kit\u003cbr\u003e\nSample Volume-10 µL\u003cbr\u003e\nShipping Conditions-Shipped in Blue Ice\u003cbr\u003e\nTarget-CTLA4,CD86\u003cbr\u003e\nTarget Class-Binding Assay\u003cbr\u003e\nTarget Species-Human\u003cbr\u003e\nTechnology-Alpha\u003cbr\u003e\nTherapeutic Area-Immuno-oncology\u003cbr\u003e\nUnit Size-5,000 assay points\u003c\/p\u003e","brand":"Revvity","offers":[{"title":"Default Title","offer_id":46774529851561,"sku":"AL3047F","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/revvity-al3047f","provider":"Iright","version":"1.0","type":"link"}
