Features:
Oncostatin M, also known as OSM, is a growth factor encoded by the OSM gene in humans. OSM is a pleiotropic cytokine that belongs to the interleukin 6 group of cytokines (also include granulocyte colony-stimulating factor), most closely resembles leukemia inhibitory factor (LIF) in both structure and function. The fully active 196 residue OSM is the predominant form isolated from activated monocytes and T lymphocytes, and corresponds to a glycoprotein of 28 Kda. It is proving important in liver development, haematopoeisis, inflammation and possibly CNS development. It is also associated with bone formation and destruction. It is a growth regulator which inhibits the proliferation of a number of tumor cell lines and stimulates normal fibroblasts, AIDS-Kaposi’s sarcoma. It regulates cytokine production, including IL-6, G-CSF (granulocyte colony-stimulating factor) and GM-CSF from endothelial cells. OSM signals through cell surface receptors that contain the protein gp130. The type I receptor is composed of gp130 and LIFR, the type II receptor is composed of gp130 and OSMR.
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.
The AlphaLISA assay is based on an AlphaLISA sandwich immunoassay involving a biotinylated anti-analyte antibody bound to Streptavidin-coated AlphaLISA Donor beads and an anti-analyte antibody conjugated to AlphaLISA Acceptor beads. Both antibodies are directed against the analyte of interest. In the presence of the target, both antibodies bind to analyte and the beads come into proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer within the Acceptor beads, resulting in emission with λmax at 615 nm. The intensity of the signal is directly proportional to the concentration of analyte present in the sample.
The AlphaLISA assay can be run in a 96- or 384-well detection plate (50 µL final). As described here, samples or standards are dispensed directly into the assay plate for the detection of the analyte of interest by AlphaLISA reagents. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally.
