WitrynaOf note, de-paraffinization and heat-induced antigen retrieval are strictly necessary for successful YAP IHC staining. Further, immunostaining using a labelled polymer-HRP system combined with diaminobenzidine (DAB), as signal-amplifying chromogen, allows strong staining results with minimal unspecific background signal. Compared to fluorescent methods used for IHC, chromogenic detection, such as DAB staining, is typically more sensitive due to the enzymatic amplification used with DAB staining and similar methods. However, it is not possible to resolve sub-cellular structures using DAB staining to the same degree as … Zobacz więcej A disadvantage of DAB is that it reacts slowly with hydrogen peroxide, even without the presence of a peroxidase enzyme.
