POD reacting with hydrogen peroxide (H2O2) catalyzes oxidative condensation of tyramide to supply extremely reactive intermediates, tyramide radicals. The activated tyramide covalently binds to electron-rich moieties which include tyrosine, phenylalanine and tryptophan at or close to the POD. The quick half-lifetime of the tyramide radicals restricts the deposition of tyramide3. https://fernandofkotv.onesmablog.com/5-easy-facts-about-cyclosporin-a-described-70206068
