Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, is synthesized principally in the stomach. It stimulates food intake and transduces signals to hypothalamic regulatory nuclei that control energy homeostasis. The peptide consists of 28 amino acids, with an octanoylation of the serine-3 residue, which is necessary for biological activity. Ghrelin is present in the peripheral circulation in two forms: acylated and non-acylated. This EIA kit specifically measures the acylated form of ghrelin. Each kit contains ghrelin (acylated) AChE-Fab'' conjugate, rat acylated ghrelin standard, rat acylated ghrelin quality control, Ellman’s reagent, EIA buffer, wash buffer, Tween 20, plates pre-coated with anti-ghrelin mouse monoclonal antibody, and complete instructions.
