The present study describes the optimisation of an autoradiography assay that provides a means to measure the in vitro potency of melanin-concentrating hormone receptor 1 (MCH(1)) antagonists in native tissues and their ex vivo receptor occupancy. Initial localisation studies demonstrated that the MCH(1) receptor radioligand [(125)I]-S36057 bound to rat(More)
We investigated the binding characteristics of angiotensin receptors and used this assay to determine the predominant enzyme capable of converting angiotensin I in the human left ventricle. In homogenates of human left ventricle, (125)I-[Sar(1),Ile(8)]angiotensin II bound with sub-nanomolar affinity, with a corresponding K(D) of 0.42+/-0.09 nM, a B(max) of(More)
Rodent vas deferens is routinely used as a native tissue preparation to assess opioid pharmacology of new compounds. The aim of this study was to investigate the effects of a selected number of opioid compounds in the human vas deferens. Stable contractions to electrical field stimulation (EFS) were inhibited by guanethidine (1 μM) and tetrodotoxin (TTX, 1(More)
