title: Prostanoid receptor assays.
abstract: Prostanoids, which include the prostaglandins (PGs) and thromboxanes (TXs), interact with a specific family of G-protein coupled receptors, of which there are known to be five distinct types, DP, EP, FP, IP and TP, each particularly sensitive to one of the five natural prostanoids, PGD₂, PGE₂, PGF₂(, PGI₂ and TXA₂, respectively. Of these, it is known that the EP receptor comprises four well-characterized subtypes: EP₁, EP₂, EP₃ and EP₄. These receptor subtypes are widely distributed throughout mammals and other species, and show particularly high levels of expression in smooth muscle and blood platelets. Despite the fact that few of these preparations express a single receptor type/subtype in isolation, a range of useful smooth muscle and platelet assays for the various prostanoid receptors are available and are presented in this unit.
