·
The primary use of this antibody conjugate is for the detection of cyclooxygenase 2 (COX-2) in murine samples by direct immunolabeling. COX catalyze the first step in the biosynthesis of prostaglandins (PGs), thromboxanes, and prostacyclins: the conversion of arachidonic acid to PGH2. Discoveries of the induction of COX by a variety of stimuli such as phorbol esters, lipopolysaccharides, and cytokines led to the hypothosis that the inducible form of COX, COX-2, is responsible for the biosynthesis of PGs under acute inflammatory conditions.1,2 COX-2 is a 72 kDa protein which has been cloned from a variety of species including human, murine, rat, and sheep.3,4,5,6
