Substrats chromogènes
Les substrats chromogènes sont des composés qui produisent un changement de couleur visible lorsqu'ils sont métabolisés par des enzymes spécifiques. Ces substrats sont largement utilisés dans les tests diagnostiques, la recherche biochimique et les dosages immuno-enzymatiques (ELISA) pour détecter et quantifier l'activité enzymatique. Le changement de couleur permet une identification visuelle facile et rapide des réactions enzymatiques, faisant des substrats chromogènes des outils essentiels en analyse de laboratoire. Chez CymitQuimica, nous proposons une large sélection de substrats chromogènes de haute qualité pour soutenir vos applications de recherche et de diagnostic.
