描述 ChemiScreen™Human CGRP1 Calcitonin Receptor Membrane Preparation 概述 Full-length human CALCRL and RAMP1 cDNAs encoding CGRP1 背景信息 The calcitonin family of peptides, which includes calcitonin, two calcitonin-related gene peptides (CGRPs), adrenomedullin, and amylin, share a disulfide-bonded loop, an amphipathic a-helix, and an amidated C-terminus. The peptides influence a variety of physiological effects, including vascular tone, food intake and bone metabolism. The biological effects of the peptides are mediated by two class B GPCRs, CT receptor (calcitonin receptor) and CL receptor (calcitonin receptor-like receptor) (Poyner et al., 2002). The pharmacology of the CT and CL receptors is strongly influenced by their association with a family of three receptor activity modifying proteins (RAMPs), which are 14-17 kD single pass transmembrane proteins. CGRP (calcitonin gene-related peptide) induces vasodilation, and its activity is primarily mediated by CGRP1, composed of CL in complex with RAMP1 (Hasbak et al., 2003). As a consequence of its role as a vasodilator, CGRP acting via CGRP1 appears to play an important role in hypertension (Deng and Li, 2005). Millipore's CGRP1 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 CGRP1 interactions with CGRP. The membrane preparations exhibit a Kd of 1.1-1.7 nM for [125I]-hCGRP. With 5 µg/well CGRP1 Membrane Prep and 1 nM [125I]-hCGRP, a greater than 15-fold signal-to-background ratio was obtained. 产品信息 演示 One package contains enough membranes for at least 200 assays (units), where an unit is the amount of membrane that will yield greater than 15-fold signal:background with 125I-labeled hCGRP at 1 nM. Liquid in packaging buffer: 50 mM Tris pH 7.4, 10% glycerol and 1% BSA with no preservatives. Packaging method: Membranes protein were adjusted to the indicated concentration in packaging buffer, rapidly frozen, and stored at -80°C. 应用 应用 Human CGRP1 GPCR membrane prepation for Radioligand binding Assays. 生物信息 品种 Human Entrez基因编号 - NM_005795.4

SIMILARITY: SwissProt: Q16602 ## Belongs to the G-protein coupled receptor 2 family.孵化条件 Membranes 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.
