Despite they seem to display very similar functions, these proteins are encoded by two independent genes sharing only ~30% identity. IL1β is synthesized as a 31 kDa precursor that is cleaved by Caspase-1 (ICE) into the active 17 kDa form, and eventually released into the extracellular space. Its production has been reported in many cell types including brain and, importantly, monocytic and periferal blood mononuclear cells. After binding to its receptor, IL-1RI, IL1β triggers a cascade of kinase signaling pathways that lead to the activation of transcription factors like NFκB and AP-1, eventually activating the expression of genes such as MIP-2 and C-reactive protein. 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.
