- The Sphingosine 1-Phosphate ELISA kit (S1P ELISA) is a sensitive and robust method for the quantification of S1P in biological samples (96-well format). \n \nSample Type: Serum/Plasma, Tissue Homogenate, and Cell culture lysate. \nSpecies of sample: The S1P antibody is likely not species specific. The S1P ELISA has been tested with S1P from human, bovine, equine, caprine, and mouse. \n Assay Range: 2 uM - 0.0625 uM \nSample Volume: 25 uL serum or plasma for duplicate points. For tissue homogenate and cell culture samples, please see the sample preparation section of the technical data sheet. \n \n \n \nProduct Background \nThe Sphingosine 1-Phosphate ELISA kit (S1P ELISA) measures S1P in biological samples. \n \nTo run the S1P ELISA, the S1P coated plate is first blocked to reduce non-specific binding. Then the S1P standards and samples are combined with an anti-S1P antibody before it is transferred to the blocked S1P coated plate. The S1P coated plate and the S1P in the sample compete for binding of the anti-S1P antibody during this step. Following an incubation and plate wash, streptavidin-HRP is added to the plate for detection of any bound anti-S1P antibodies (labeled with biotin). After an additional incubation and plate wash, TMB substrate is added to the plate. The colorometric TMB reaction is stopped with the addition of 1N sulfuric acid and the plate is measured at 450 nm absorbance. The concentration of S1P, in the samples, is determined when compared to the S1P standard curve. \n \nSphingosine 1-Phosphate (S1P) is a key component of the sphingolipid signaling cascade. S1P initiates a proliferative, pro-angiogenic and anti-apoptotic sequence of events contributing to cancer progression. Recently, scientific literature has suggested that S1P is a potent tumorigenic growth factor that is likely released from tumor cells and that S1P may be a novel biomarker for early stage cancer detection. Sphingosine kinase has also been shown to be up-regulated in a variety of cancer types (S1P is produced via the activity of sphingosine kinase phosphorylating sphingosine). \nFeatured in Publications \n1.
