The AlphaLISA® immunoassay kit for mouse IL-5 enables the quantitative determination of mouse interleukin-5 in buffered solution and cell culture supernatants using a homogeneous AlphaLISA assay (no wash steps).
For research use only. Not for use in diagnostic procedures.
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.
Interleukin 5 (IL-5) is a pleiotropic cytokine produced primarily by Th2 cells, mast cells, and eosinophils. It is synthesized as a precursor maturing into an active protein which is heavily glycosylated and covalently linked in a homodimer by a disulfide bond. IL5 supports the proliferation and differentiation of mouse B cells, and enhances IgM, IgG1, IgA, IgE secretion. Its key function is to mediate activation, maturation and survival of eosinophils and is strongly implicated in the pathogenesis of asthma and other hypereosinophilic inflammatory conditions.
