Highly recommended for in vitro stabilization and crystallization of melatonin receptors.
By Anonymous on 10/11/2022
Assay Type: In Vitro
Species: Human

After trying many other melatonin receptor ligands, this has become our gold standard for stabilizing MT1 and MT2 melatonin GPCRs for in vitro studies. Given its high potency, relatively low micromolar concentrations are sufficient to achieve the desired effect. We found that it sufficiently stabilizes MTRs for crystallization purposes. Additionally, in cell based GPCR activity assays, it is able to achieve an efficacy as high as, or higher, than the endogenous ligand melatonin. Highly recommended if you value maximum stabilization and/or efficacy

Dissolves well in DMSO
