POD reacting with hydrogen peroxide (H2O2) catalyzes oxidative condensation of tyramide to generate hugely 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 short 50 %-lifetime of the tyramide radicals restricts the deposition of tyramide3. https://archimedesa221lwh4.wikimillions.com/user
