The Glucagon-Like Peptide-1 (GLP-1 (7-36 amide)) is a 30 oligopeptide, generated from proglucagon, secreted by the enteroendocrine L cells of the small and large intestine, in a nutrient-dependent manner (some GLP-1 (7-36 amide) is also produced by the pancreatic α-cells and in the central nervous system). Circulating GLP-1 (7-36 amide) levels rapidly increase shortly after ingestion, playing a significant role in the inhibition of gastric emptying and food intake. It is also important for blood glucose homeostasis through the stimulation of insulin biosynthesis and secretion, islet proliferation, and the inhibition of glucagon secretion. Moreover, it regulates hypothalamic-pituitary function and GLP-1 activated circuits mediate the central nervous system response to aversive stimulation. In the circulation, the active form of GLP-1 (GLP-1 (7-36 amide)) is promptly inactivated by the dipeptidyl peptidase IV (DP IV).
AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.
