PGE2 is one of the primary COX products of arachidonic acid and one of the most widely investigated prostaglandins. Its activity influences inflammation, fertility and parturition, gastric mucosal integrity, and immune modulation.1,2,3,4 The effects of PGE2 are transduced by at least four distinct receptors designated EP1, EP2, EP3, and EP4.5 Affinity constants (Kd) of PGE2 for these receptors range from 1-10 nM depending on the receptor subtype and tissue.

Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
