Peroxidase Substrate

ImmPACT DAB is a formula of diaminobenzidine-based peroxidase substrate. The product’s sensitivity allows a dark, crisp, brown precipitate to be generated. It is offered for use with immunohistochemical staining and membrane-based blot detection with any horseradish peroxidase-based detection reagents. It is resistant to ethanol and organic solvents, enabling dehydration and permanent mounting of stained preparations. Sharp color deposition on tissue sections allows contrast with traditional counterstains like hematoxylin or in combination with other enzyme substrates for multiple antigen labeling.
