Antigen: mouse COX-2 amino acids 570-598 (DPQPTKTATINASASHSRLDDINPTVLIK) · Host: rabbit · Application(s): FC, IF, and WB · The primary use of this antibody conjugate is for the detection of cyclooxygenase 2 (COX-2) in mouse 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, mouse, rat, and sheep.^3,4,5,6
