Sustratos cromogénicos
Los sustratos cromogénicos son compuestos que producen un cambio de color visible cuando son metabolizados por enzimas específicas. Estos sustratos se utilizan ampliamente en ensayos diagnósticos, investigaciones bioquímicas y ensayos de inmunoabsorción enzimática (ELISA) para detectar y cuantificar la actividad enzimática. El cambio de color permite una identificación visual rápida y sencilla de las reacciones enzimáticas, lo que convierte a los sustratos cromogénicos en herramientas esenciales en el análisis de laboratorio. En CymitQuimica, ofrecemos una amplia selección de sustratos cromogénicos de alta calidad para apoyar sus aplicaciones de investigación y diagnóstico.
