Characterization
Description(s):Obesity increases the risk for the metabolic syndrome, diabetes, hypertension, atherosclerosis, and thrombosis. A number of proteins have been identified to be relevant to the development of the metabolic syndrome, diabetes, and cardiovascular disease with obesity. Plasma concentrations of these proteins are usually measured by ELISA. To systematically examine the effects, Signosis developed an ELISA strip which allows simultaneous determination of 8 obesity associated cytokines. The difference of these proteins between two samples can be determined through data comparison. Therefore, it facilitates the discovery of the change of these proteins in different samples.

8 - 2000 pg/mL

Principle
Each well of the strip is coated with a specific capture antibody to detect its corresponding cytokine in the sample. Therefore, eight different proteins can be measured simultaneously. In this assay, the test sample initially reacts with the solid phase capture antibody, resulting in the cytokine being bound to the well. The wells are then washed to remove unbound proteins, and biotin-linked antibodies are added to bind to the cytokines. After washing away the unbound antibodies, Streptavidin-HRP conjugate is added to form a complex with the antibody-bound cytokines. After incubation, the wells are washed to remove unbound Streptavidin-HRP conjugate. The HRP substrate, TMB, is then added and forms a blue color when the HRP-linked antibodies are detected. The reaction is then terminated with Stop Solution, which changes the color from blue to yellow. The cytokine concentration in each well is directly proportional to its color intensity and can be quantified by measuring its optical density at 450 nm (OD450) in a microplate reader.
