title: alpha 2A/D-Adrenoceptor subtype predominates also in the neonatal rat spinal cord.
abstract: alpha 2-Adrenoceptors are remarkably regulated by developmental factors. In this study alpha 2-adrenoceptor subtypes have been characterised in neonatal and adult rat spinal cords. In saturation experiments, a 5% proportion of [3H]rauwolscine binding has a high affinity component, representing the alpha 2C-subtype in both tissues. Competition studies with [3H]RX821002 indicate that in both tissues the alpha 2A/D subtype is expressed similarly.
