mu (MOP) Human Opioid GPCR Cell Based Agonist & Antagonist cAMP LeadHunter Assay - TW
OVERVIEW
DOCUMENTS/REFERENCES
Biological Information
Background Information:
Opiate receptors belong to the superfamily of G protein-coupled seven transmembrane proteins. G-protein-coupled receptors constitute one of the major signal transduction systems in eukaryotic cells. Coding sequences for these receptors, in those regions believed to contribute to the agonist-antagonist binding site, are strongly conserved across mammalian species. Opiate receptors are found primarily, but not entirely, in the central nervous system. Opiate μ receptor agonism may be analgesic, reduce gastrointestinal transit and adversely affect respiration.

Testing Information
Procedure Summary:
Human recombinant Opiate μ receptor expressed in CHO-K1 cells are used. Test compound and/or vehicle is incubated with the cells (4 x 10^5/ml) in modified HBSS pH 7.4 buffer at 37°C for 30 minutes. The reaction is evaluated for cAMP levels by TR-FRET. Test compound-induced cAMP increase by 50 percent or more (≥50%) relative to the 10 μM DAMGO control response indicates possible opiate m receptor agonist activity. Test compound-induced inhibition of the 10 nM DAMGO induced cAMP response by 50 percent or more (≥50%) indicates receptor antagonist activity.
Incubation:
30 min at 37°C
Control Inhibitor:
Naltrexone
Control Activator:
DAMGO
Criteria For Significance:
≥ 50% decrease in cAMP relative to DAMGO response, ≥ 50% Inhibition of DAMGO-induced cAMP decrease
Test Concentration / Dose:
Compounds are screened at 10, 3, 1, 0.3, 0.1, 0.03, 0.01 and 0.003 μM
Test Sample Requirements:
75 μl of 10 mM stock or 1 mg (pre-weighed) powder (assuming FW ≦500 and purity 100%)
Minimum Order Quantity:
16
Turnaround Time
Standard:
20 Business Days
