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.
FAS Ligand (FASL), also known as CD95L, is a transmembrane protein expressed on cytotoxic T cells. It binds to CD95 regulatory T-cells. Upon binding to its receptor, the protein forms trimers that initiate apoptosis of the cells. The protein is involved in regulation of cytotoxic T-cells levels, protection of self-immune effects and control of inflammation. However, some cancer cells can overexpress FASL, blocking the immune response from destroying the tumor.

The introduction of enzyme-linked immunosorbent assays (ELISAs) in the early 1970’s offered researchers a non-radiometric immunoassay platform without compromising sensitivity. Over the last 50 years scientists have made huge strides in disease research and drug discovery and a demand for greater ...
