DescriptionChemiSCREEN™ Membrane Preparation Recombinant Human sst1 Somatostatin Receptor
OverviewHuman sst1
Background InformationSomatostatin, a 14 or 28 amino acid peptide, inhibits hormone secretion from exocrine glands, and displays an antiproliferative activity on a number of cell types. A family of 5 Gi-coupled receptors mediates the effects of somatostatin. The classical activity of somatostatin of inhibiting growth hormone release from the pituitary appears to be mediated by sst1. In addition, sst1 functions as an inhibitory autoreceptor on somatostatin neurons in the hippocampus, hypothalamus, basal ganglia and retina (Thermos et al., 2006). The somatostatin receptors are targets for anticancer drugs and for treatment of hormonal dysfunction. Millipore's sst1 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 agonists and antagonists of sst1. The membrane preparations exhibit a Kd of 1.4 nM for [125I]- somatostatin-14. With 0.5 nM [125I]- somatostatin-14, 5 μg/well sst1 Membrane Prep yields greater than 12 fold signal-to-background ratio.

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, an FC 96-well harvest plate (Millipore cat. # MAHF C1H) 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]- somatostatin-14 (PerkinElmer NEX389)
Wash Buffer: 50 mM HEPES, pH 7.4, 500 mM NaCl, 0.1% BSA, filtered and stored at 4°C.
