Substratos Cromogénicos
Os substratos cromogênicos são compostos que produzem uma mudança de cor visível quando são metabolizados por enzimas específicas. Esses substratos são amplamente utilizados em ensaios diagnósticos, pesquisa bioquímica e ensaios imunoenzimáticos (ELISA) para detectar e quantificar a atividade enzimática. A mudança de cor permite uma identificação visual fácil e rápida das reações enzimáticas, tornando os substratos cromogênicos ferramentas essenciais na análise laboratorial. Na CymitQuimica, oferecemos uma seleção diversificada de substratos cromogênicos de alta qualidade para apoiar suas aplicações de pesquisa e diagnóstico.
