Arachidonic acid ELISA kits are assays designed to detect the polyunsaturated fatty acid arachidonic acid (AA). It is released through the action of phospholipase A2 in cell membranes and is a precursor in the synthesis of prostaglandins and leukotrienes. It is abundant in the liver, brain, and muscles. It is an important mediator of inflammation and is involved in many metabolic processes as a cellular messenger. Arachidonic acid can be obtained directly from food or from the conversion of the essential fatty acid, linoleic acid. Altered levels of arachidonic acid in the brain have been associated with Alzheimer’s disease and bipolar disorder. Visit the supplier page for more information about detection range and reactivity.
