Product name4-Chloro-1-naphthol, Chromogenic peroxidase substrate
DescriptionChromogenic peroxidase substrate.
Chromogenic peroxidase substrate that results in a precipitate that is blue to blue-purple in color and can be observed visually. Used for both western blotting and immunohistochemical staining. Can be used as a substitute in the myeloperoxidase stain for benzidine compounds, which are considered to be carcinogenic.
Storage instructionsStore at -20°C. Store under desiccating conditions. The product can be stored for up to 12 months.
