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 involved in the development of the obesity related metabolic syndrome, diabetes, and cardiovascular diseases. These include adiponectin, leptin, TNFa, IGF-1, Resistin, TGFß, IL-6, and PAI-1. 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 cytokines. The difference of these proteins between two samples can be determined through data comparisons. Therefore, it facilitates the discovery of the change of these proteins in different samples.

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. 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 the samples to bind to the cytokines. After washing away the unbound antibodies, Streptavidin-HRP conjugate is added to the sample to form a complex with the antibody-bound cytokines. After incubation, the wells are washed to remove unbound Streptavidin-HRP conjugate. HRP luminescent substrate is then added to detect the presence of antibody-bound cytokines. The cytokine concentration in each well is directly proportional to its luminescent intensity, which is measured as relative light units (RLU) by a microplate reader.
