ChemiSCREEN Membrane Preparation Recombinant Human GLP-1

Descrição detalhada : Human GLP-1, Glucagon-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 mug/well GLP-1 Receptor Membrane Prep and 0.5 nM [125I]-GLP-1, a greater than 9-fold signal-to-background ratio was obtained.
