abstract：:The binding of oxytocin (OT) to receptors in rabbit amnion cells stimulates PGE2 release. We previously studied the binding characteristics, changes in receptor concentration during pregnancy, and agonist specificity of OT action on amnion cells. In this study the molecular size of OT receptors in rabbit amnion was es...
