Description

Limit of detection: 1.5 pg/ml after 20 hour immunological incubation; 4 pg/ml after 3 hour immunological incubation · 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. This EIA is based on a double-antibody sandwich technique. The wells of the plate supplied with the kit are coated with a monoclonal antibody specific to the C-terminal part of ghrelin. This antibody will bind to any ghrelin introduced into the wells (standard or sample). The AChE - Fab' conjugate which recognizes the N-terminal part of acylated ghrelin is also added to the wells. This allows the two antibodies to form a sandwich by binding on different parts of the human acylated ghrelin. Each kit contains ghrelin (acylated) AChE-Fab' conjugate, human acylated ghrelin standard, human 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.
