• Pre-filtered and ready-to-use
• Storage at 4 °C

Chloronaphthol reacts with HRP to form a distinct blue to blue-purple product to localize and visualize the activity of peroxidase-conjugated antibodies on blots or fixed tissue samples. Its alcohol-solubility is a property that can be utilized in certain double-staining applications.
