Programmed death ligand 1 (PD-L1), also known as cluster of differentiation 274 (CD274) or B7 homolog1 (B7-H1) belongs to the growing B7 family of immune proteins and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. Human PD-L1 is constitutively expressed in several organs such as heart, skeletal muscle, placenta and lung, and in lower amounts in thymus, spleen, kidney and liver. PD-L1, together with PD-L2, are two ligands for PD-1 (programmed death 1), a member of the CD28 family of immunoreceptors. By binding to PD-1 on activated T-cells and B-cells, PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly, it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.

AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated 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 causes 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.

Soluble PD-L1 Detection in Cellular Supernatants Using AlphaLISA

When PD-1, which is expressed on the T cell, binds to PD-L1 expressed on the tumor cell, the T cell response is suppressed. Utilization of this pathway leads to tumor immune escape and promotes tumor cell growth. In fact, PD-L1 expression increases with tumor severity in many types of cancer. Rel ...
