Microvessels isolated from rat cerebral cortex consist mainly of capillaries (greater than 85%). Fresh, intact microvessel preparations have been analyzed by radioligand binding techniques for muscarinic receptors. Scatchard analysis of specific quinuclidinyl benzilate (QNB) binding indicates that microvessels possess a large number of muscarinic sites (914 fmol/mg protein) of high affinity (KD = 0.034 nM). The association and dissociation rate constants (0.37 min-1 nM-1 and 0.0067 min-1, respectively) yield an equilibrium KD of 0.018 nM. Displacement of [3H]QNB by muscarinic ligands and control substances is typical of muscarinic receptors. The results indicate that cerebral microvessels possess a large population of muscarinic receptors.
