POD reacting with hydrogen peroxide (H2O2) catalyzes oxidative condensation of tyramide to provide very reactive intermediates, tyramide radicals. The activated tyramide covalently binds to electron-wealthy moieties including tyrosine, phenylalanine and tryptophan at or close to the POD. The small 50 percent-life of the tyramide radicals restricts the deposition of tyramide3. https://brianf443rcm6.wikitelevisions.com/user
