Cyclooxygenase Activity Assay

Assay Genie's Cyclooxygenase Activity Assay provides a sensitive and high-throughput method to detect the peroxidase activity of Cyclooxygenase (COX) in biological samples or purified/crude enzyme preparations. The kit includes COX-1 and COX-2 specific inhibitors to differentiate the activity of COX-1 and COX-2 as well as other peroxidases, which may be present in the sample. The Cyclooxygenase Activity Assay has a detection limit of 6 µU/mg.

Cyclooxygenase Background

Cyclooxygenase (COX), also known as prostaglandin-endoperoxide synthase (PTGS, EC, is an enzyme that is responsible for the formation of important biological mediators called prostanoids, including prostaglandins, prostacyclin and thromboxane. COX is the central enzyme in the biosynthetic pathway to prostanoids from arachidonic acid. There are two known isoenzymes: COX-1 and COX-2. COX-1 is constitutively expressed in many tissues and is the predominant form in gastric mucosa and in kidney. COX-2 is not expressed under normal conditions in most cells, but elevated levels are observed during inflammation. Pharmacological inhibition of COX by nonsteroidal anti-inflammatory drugs (NSAID) can provide relief from the symptoms of inflammation and pain.
