POD reacting with hydrogen peroxide (H2O2) catalyzes oxidative condensation of tyramide to provide extremely reactive intermediates, tyramide radicals. The activated tyramide covalently binds to electron-rich moieties such as tyrosine, phenylalanine and tryptophan at or close to the POD. The small half-lifetime of the tyramide radicals restricts the deposition of tyramide3. https://llahz211kwh4.wikiadvocate.com/user
