Interleukin 10 (IL-10),initially designated cytokine synthesis inhibitor,is a pleiotropic cytokine that inhibits the production of a number of cytokines (including IL-1,GM-CSF,TNF,IL-6,IL-8,IL-12 and IFN-gamma) by activated Th1 cells,NK cells,and monocytes/macrophages. IL-10 has also been shown to inhibit macrophage cytotoxic activity and to stimulate the proliferation and differentiation of B cells,mast cells,and thymic T cells. Mouse IL-10 is produced by a wide variety of cells,including activated Th2 cells,fetal thymocytes,monocytes/macrophages,keratinocytes,B cells,and glial cells. Mouse IL-10 cDNA encodes a 178aa residue precursor protein with a hydrophobic signal peptide that is cleaved to generate the 160aa residue mature protein. At the amino acid sequence level,there is approximately 73% identity between mouse and rat or mouse and human IL-10. Although human IL-10 is active on mouse cells,mouse IL-10 does not show species cross-reactivity on human cells.Sample Type:Cell culture supernatants,serum,plasma,and tissueIntended Use:The Mouse IL-10 BioAssay ELISA Kit is an enzyme-linked immunosorbent assay for the quantitative detection of Mouse IL-10 concentrations in cell culture supernatants,serum,plasma,and tissue.Sensitivity:7pg/mlRange:15.625-1000pg/mlSpecificity:Recognizes mouse IL-10. There was no detectable cross reactivity with any of the tested proteins following IL-1,2,3,4,5,6,8,12,TNF,VEGF,TGF and IFN.Sample Volume:100ul/wellTest Principle:This assay employs the Sandwich immunoassay technique. An anti-m IL-10 monoclonal coating antibody is adsorbed onto microwells. IL-10 present in the sample or standard binds to antibodies adsorbed to the microwells. Following incubation unbound sample or standard are removed during a wash step. a Biotinylated anti-m IL-10 antibody is added and binds to IL-10 captured by the first antibody. Following incubation unbound Biotinylated anti-m IL-10 antibody is removed during a wash step. A Streptavidin-HRP is added and binds to Biotinylated anti-m IL-10 antibody. Following incubation unbound Streptavidin-HRP is removed during a wash step. A colored product is formed in proportion to the amount of IL-10 present in the sample. The reaction is terminated by addition of acid and absorbance is measured at 450nm. A standard curve is prepared from seven IL-10 standard dilutions and IL-10 sample concentration determined.Kit Components:Aluminium pouches with a Microwell Plate: 8x12Standard: 2xVialBiotinylated antibody: 2xVialStreptavidin-HRP: 2xVialAssay Buffer (25ml/Vial): 2xVialWash Buffer Concentrate 20x (30ml/Vial): 1xVialTMB Substrate Solution: 1x12mlStop Solution (12ml/Vial): 1xVialPlate Covers- Adhesive strips: 3xstripsInstruction: 1xStorage and Stability:Store powder at 4°C liquid at -20°C.
