Merck Millipore Glucagon Receptor Membranes 200U

Glucagon is a 29-amino acid peptide that stimulates glycogenolysis and gluconeogenesis in the liver to increase blood glucose. The receptor for glucagon is a class 2 (or class B) GPCR that signals through Gs to stimulate cAMP production (Mayo et al., 2003). Mice lacking the glucagon receptor have mild hypoglycemia after fasting, and exhibit hyperplasia of pancreatic α-cells (Gelling et al., 2003). Because of its role in promoting hyperglycemia, the glucagon receptor presents a potential target for treatment of diabetes. Chemicon's glucagon 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 of antagonists of glucagon receptor interactions and its ligands. The membrane preparations exhibit a Kd of 3.09 nM for [125I]-glucagon. With 1 nM [125I]-glucagon, 5 or 10 μg/well glucagon receptor Membrane Prep yields greater than 10-fold signal-to-background ratio.
