AlphaLISA features:
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.
4-1BBL, also known as CD137L or TNFSF9, is a type II transmembrane receptor protein expressed on activated B cells, monocytes, neutrophils, and neurons. It binds to 4-1BB on activated CD4+ and CD8+ T cells. Ligation of 4-1BBL results in survival of T cells during infection. A soluble form of 4-1BBL has been shown to be cleaved from the surface of activated B cells. There are many drug targets centered on interrupting the binding of 4-1BB to 4-1BBL. These are focused on stimulating immune response to cancers.

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 assay throughput and sensitivity has evolved. In response, more robust immunoassays have been developed to address some of the limitations of the standard, colorimetric ELISA.
Find out about the most common limitations of traditional ELISAs and how different ELISA alternative technologies address these limitations.
