A novel long-acting VIP analog in the guinea pig trachea in vitro.

abstract：:The present studies were undertaken to better characterize the pharmacological properties of oxytocin receptors (OTRs) of the porcine kidney cell line, LLC-PK1, in their natural membranous environment and after solubilization. In intact membranes, binding of a selective radioligand was rapid, reversible, saturable, an...
