Definitions
- 5-hydroxytryptamine-7 The recently identified human 5-hydroxytryptamine-7 (5-HT7) receptor subtype has been cloned, and the extensive distribution of its mRNA has been reported. Highest levels of 5-HT7 receptor mRNA have been observed in the hypothalamus, thalamus. brainstem and hippocampus, while lower levels have been found in the cerebral cortex, striatum, olfactory bulb and olfactory tubercle. The presence of 5-HT7 mRNA is not limited to the brain, it has also been found in peripheral tissues, namely spleen, stomach, ileum, intestine, coronary artery, descending colon, smooth muscle cells and heart.

- the diluted membranes are kept cold on ice and immediately used in subsequent binding experiments.
- Binding experiments are performed in a 96 well microtiter plate format, in a total volume of 200 ⁇ l. To each well is added: 80.0 ⁇ l of incubation buffer made in 50 mM Tris.HCl buffer, pH 7.4 and containing 10.0 mM MgC12 and 0.5 mM EDTA; 20 ⁇ l of [ ⁇ ] LSD (S.A., 86.0 CiJ mmol, Amersham Life Science), 5.0 - 6.0 nM.
- the dissociation constant, K D of [ 3 H]LSD at the human serotonin 5-HT7 receptor is 2.9 nM, as determined in saturation studies with increasing concentrations of [ 3 H]LSD.
