Native Sheep Cyclooxygenase 1

Cat No.
NATE-0149
Description
COX-1 catalyzes the conversion of arachidonic acid to prostaglandin H2 (the first step in the biosynthesis of prostaglandins, thromboxanes, and prostacyclins). It is involved in the homeostatic role of eicosanoids and constitutively almost all animal tissues. Has an apparent KM of 8.3 μM for arachidonic acid.
