DAB-4HCl (3-3’-Diaminobenzidine tetrahydrochloride) 30ML Vials
Starting at: $97.00
Chromogen of choice for immunoperoxidase techniques. The brown reaction product is highly insoluble, and will not diffuse from the site of localization. The color does not fade, and therefore, slides can be saved as a permanent record. The reaction product also chelates with osmium tetroxide and becomes electron dense for use in electron microscopy.
