Features:
Human interleukin 11 (IL11) is a non-glycosylated protein of 23 kDa (179 amino acids). It is produced by bone marrow stromal cells (fibroblasts) and also by a variety of mesenchymal cells. IL11 stimulates megakaryocytopoiesis, activates osteoclasts, inhibits epithelial cell proliferation and apoptosis, and inhibits macrophage mediator production. IL-11 also possesses anti-inflammatory activity, and has been proposed as a therapeutic agent in the treatment of chronic inflammatory diseases, such as Crohn's disease and rheumatoid arthritis. IL11 activity is mediated by the IL-11 receptor (IL-11R) that has been reported in a wide variety of cells and tissues. IL11 binds to the IL-11R protein alone with low affinity; the affinity increases when IL-11R is associated with is signal transducer: gp130.
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.

For the detection of three biomarkers in complex sample matrices, the AlphaLISA and Electrochemiluminescent (ECL) assay technologies were shown to have similar: Assay windows (linear dynamic range), Lower and upper detection limit, Intra-and inter-assay precision (lower % CV) The advantages of using AlphaLISA over ECL are: Shorter total assay duration No wash steps No shaking Lower sample volume requirement for equivalent performance Less expensive instrument and plates required
The AlphaLISA® assay is a homogeneous immunoassay alternative to classical ELISA. AlphaLISA assays were originally utilized to detect analytesin cell cultures upernatants or serum/plasma samples.
