Cotinine binding on nicotinic acetylcholine receptors was investigated by radioligand essay. 125I-alpha-bungarotoxin was used rather than 3H- nicotine,
Nicotinic acetylcholine receptors (nAChRs) are a superfamily of ligand-gated ion channels which mediate nicotine reward, dependence and addiction.
Has anyone had any experience with this? Or know anything. I've been trying to quite smoking and have noticed some quite interesting
