Substrati cromogenici
I substrati cromogeni sono composti che producono un cambiamento di colore visibile quando vengono metabolizzati da specifici enzimi. Questi substrati sono ampiamente utilizzati nei test diagnostici, nella ricerca biochimica e negli immunoassay enzimatici (ELISA) per rilevare e quantificare l'attività enzimatica. Il cambiamento di colore consente una facile e rapida identificazione visiva delle reazioni enzimatiche, rendendo i substrati cromogeni strumenti essenziali nell'analisi di laboratorio. Presso CymitQuimica, offriamo una vasta selezione di substrati cromogeni di alta qualità per supportare le vostre applicazioni di ricerca e diagnostica.
