      DescriptionChemiSCREEN™ Membrane Preparation Recombinant Human GLP-1
      OverviewHuman GLP-1
      Background InformationGlucagon-like peptide-I (GLP-1), a member of the glucagon-secretin peptide family, is secreted from L-cells of the small intestine and binds to a class B (class 2) G protein-coupled receptor (Mayo et al. 2003). The GLP-1 receptor is expressed in pancreatic beta cells and upon binding to GLP-1, it couples to Gs to increase cAMP levels and insulin secretion (Drucker et al. 1987). In addition, GLP-1 has been shown to delay gastric emptying and regulate appetite. Therefore, the GLP-1 receptor represents an important therapeutic target for type II diabetes, and a degradation-resistant analog of GLP-1, exanatide, is used clinically in combination with other glucose-lowering drugs to control type II diabetes (D’Alessio et al. 2004). Millipore's GLP-1 receptor membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening for agonists and antagonists at the GLP-1 receptor. The membrane preparations exhibit a Kd of 0.27 nM for [125I]-GLP-1. With 10 μg/well GLP-1 Receptor Membrane Prep and 0.5 nM [125I]-GLP-1, a greater than 9-fold signal-to-background ratio was obtained.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P43220 # This is a receptor for glucagon-like peptide 1. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase.
      SIZE: 463 amino acids; 53060 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      SIMILARITY: SwissProt: P43220 ## Belongs to the G-protein coupled receptor 2 family.
      Incubation ConditionsMembranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h. Prior to filtration, a GF/C 96-well filter plate is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4, 0.5% BSA. Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer. The plate is dried and counted.

      Binding buffer: 50 mM Hepes, pH 7.4, 5 mM MgCl2, 1 mM CaCl2, 0.2% BSA, filtered and stored at 4°C
      Radioligand: [125I] GLP-1(7-36) (Perkin Elmer # NEX308)
      Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4°C.
