Kit Principle Aviva Systems Biology Arachidonic acid ELISA Kit (OKEH02583) is based on a competitive enzyme immunoassay technique. The microtiter well-plate in this kit has been pre-coated with an anti-Arachidonic acid antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated Arachidonic acid and incubated. The Arachidonic acid found in the sample or standards competes with the biotinylated Arachidonic acid for limited binding sites on the immobilized anti-Arachidonic acid antibody. Excess unbound biotinylated Arachidonic acid and sample or standard Arachidonic acid is washed from the plate. Avidin-HRP conjugate is added, incubated and washed. An enzymatic reaction is then produced through the addition of TMB substrate which is catalyzed by the immobilized HRP to generate a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration is measured by reading the absorbance at 450 nm which is quantitatively proportional to the amount of biotinylated Arachidonic acid captured in the well and inversely proportional to the amount of Arachidonic acid which was contained in the sample or standard.

Protein Name Arachidonic acid
Description of Target Arachidonic acid is a polyunsaturated fatty acid that is present in the phospholipids (especially phosphatidylethanolamine, phosphatidylcholine, and phosphatidylinositides) of membranes of the body's cells, and is abundant in the brain, muscles, liver. Arachidonic acid (AA, sometimes ARA) is a polyunsaturated omega-6 fatty acid 20:4(ω-6). It is the counterpart to the saturated arachidic acid found in peanut oil.
