Principle of the Assay: A-GHR ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-A-GHR antibody and an A-GHR-HRP conjugate. The assay sample and buffer are incubated together with A-GHR-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the A-GHR concentration since A-GHR from samples and A-GHR-HRP conjugate compete for the anti-A-GHR antibody binding site. Since the number of sites is limited, as more sites are occupied by A-GHR from the sample, fewer sites are left to bind A-GHR-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The A-GHR concentration in each sample is interpolated from this standard curve.

This gene encodes the ghrelin-obestatin preproprotein that is cleaved to yield two peptides, ghrelin and obestatin. Ghrelin is a powerful appetite stimulant and plays an important role in energy homeostasis. Its secretion is initiated when the stomach is empty, whereupon it binds to the growth hormone secretagogue receptor in the hypothalamus which results in the secretion of growth hormone (somatotropin). Ghrelin is thought to regulate multiple activities, including hunger, reward perception via the mesolimbic pathway, gastric acid secretion, gastrointestinal motility, and pancreatic glucose-stimulated insulin secretion. It was initially proposed that obestatin plays an opposing role to ghrelin by promoting satiety and thus decreasing food intake, but this action is still debated. Recent reports suggest multiple metabolic roles for obestatin, including regulating adipocyte function and glucose metabolism. Alternative splicing results in multiple transcript variants. In addition, antisense transcripts for this gene have been identified and may potentially regulate ghrelin-obestatin preproprotein expression. [provided by RefSeq, Nov 2014]
