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.

HLA-E, also known as MHC class I antigen E, official full name as major histocompatibility complex, class I, E, is a protein that in humans is encoded by the HLA-E gene. HLA-E is a heterodimer consisting of a heavy chain and a light chain (β-2 microglobulin). The heavy chain is approximately 45 kDa and anchored in the membrane. HLA-E has a very specialized role in cell recognition by natural killer cells (NK cells). HLA-E binds to CD94/NKG2C to regulate NK cell cytolysis activities. This kit has been designed for the detection of Human HLA-E in cell lysate and cell culture supernatants.
